Using minted inside listing causes Problems

Question

I am farly new to LateX, so please be kind ;-). I am using minted to show off some code I wrote. I want the code to have a caption and label so i can refer to it from the text and have it appear in the "List of Listings" at the bottom of my document. Thats why I put minted inside this listing thing.

This is my definition for minted - so i dont need to specify everything mutliple times:

\usepackage[chapter]{minted}
\newminted{glsl}{
   mathescape,
   linenos,
   numbersep=5pt,
   gobble=2,
   frame=lines,
   framesep=2mm}

And this is the code inside my Text.

\begin{listing}[H]
 \caption{Berechnung der Runlength für einen bestimmten Pixel}
 \begin{glslcode}
    void getRlHor() {
        for(int j=1; j < maxSize; j++) {
            int xRunlength = px + j;
            if(xRunlength > imgWidth)
                break;
            nextGreyV = getGreyValue(xRunlength, py);
            if(currentGreyV == nextGreyV) {
                rlHor++;
            }else{
                break;
            }
        }
    }
 \end{glslcode}
 \label{lis:getRlHor}
\end{listing}

I am using \begin{listing} because i saw it on multiple examples with minted. But this is giving me the trouble.

Here is the error report i am getting: There are always these 8 lines that pop off.

Something's wrong--perhaps a missing \item. \addvspace {10\p@ }

It seems when i delete the main.lol file. I can compile once without an error. If i write another sentence and then compile again, i get these errors mentioned above. But thats a buggy workarround.

Help is appreciated!!

Edit: I feel a bit dump for not realising this. When i open the main.lol file, here is what it shows

\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\contentsline {listing}{\numberline {3.1}{\ignorespaces Spezialf\"alle     abfangen und Randbedingungen setzen}}{8}{listing.3.1}% 
\contentsline {listing}{\numberline {3.2}{\ignorespaces Berechnung der              Runlength f\"ur einen bestimmten Pixel}}{8}{listing.3.2}% 
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }

The bottom 8 of these (\addvspace {10\p@ }) show red after i compile. I thought it came from the code i put in, since the error started occuring after i put the code it. I cant really post the whole document, since i had to post like 8 whole files here.

This document runs without error, so the error you show must be generated by code you have not shown. please edit the question to have a complete document as below which generates the error shown.

\documentclass{report}


\usepackage{float}
\usepackage[chapter]{minted}
\newminted{glsl}{
   mathescape,
   linenos,
   numbersep=5pt,
   gobble=2,
   frame=lines,
   framesep=2mm}

\begin{document}

\listoflistings

\begin{listing}[H]
 \caption{Berechnung der Runlength für einen bestimmten Pixel}
 \begin{glslcode}
    void getRlHor() {
        for(int j=1; j < maxSize; j++) {
            int xRunlength = px + j;
            if(xRunlength > imgWidth)
                break;
            nextGreyV = getGreyValue(xRunlength, py);
            if(currentGreyV == nextGreyV) {
                rlHor++;
            }else{
                break;
            }
        }
    }
 \end{glslcode}
 \label{lis:getRlHor}
\end{listing}
\end{document}

Following the edit, this document produces the error shown, on line 15

\documentclass{article}

\begin{document}

\makeatletter

\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\contentsline {listing}{\numberline {3.1}{\ignorespaces Spezialf\"alle     abfangen und Randbedingungen setzen}}{8}{listing.3.1}% 
\contentsline {listing}{\numberline {3.2}{\ignorespaces Berechnung der              Runlength f\"ur einen bestimmten Pixel}}{8}{listing.3.2}% 
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\end{document}

It can be fixed by adding a blank line as in:

\documentclass{article}

\begin{document}

\makeatletter

\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\contentsline {listing}{\numberline {3.1}{\ignorespaces Spezialf\"alle     abfangen und Randbedingungen setzen}}{8}{listing.3.1}% 
\contentsline {listing}{\numberline {3.2}{\ignorespaces Berechnung der              Runlength f\"ur einen bestimmten Pixel}}{8}{listing.3.2}%

\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\addvspace {10\p@ }
\end{document}

So the error is in code you have not shown that is writing

 \addvspace {10\p@ }

to the lol file. Either it should not be written at all (which is the default behaviour) or it should write a blank like or \par to make sure it is in vertical mode before adding vertical space.
