glossaries, glossary-longragged: problem with redefining \glossaryentryfield

Question

I'm encountering a weird problem when changing my list of acronyms from the long to the longragged style. This is an example for illustration:

\documentclass{article}

\usepackage[acronym,nomain,sanitize={description=false,symbol=false}]{glossaries}
\usepackage{glossary-longragged}
\makeglossaries

\newglossarystyle{longraggeduc}{%
%  \glossarystyle{long}%  <-- works
  \glossarystyle{longragged}%  <-- does not work
  \renewcommand*\glossaryentryfield[5]{%
    \glstarget{##1}{##2} & \makefirstuc{##4}##3\glspostdescription\space##5\\
  }
}

\newacronym{acr:abc}{ABC}{a b c}
\newacronym{acr:def}{DEF}{d e f}

\begin{document}
\gls{acr:abc} \gls{acr:def}

\printglossary[type=\acronymtype,style=longraggeduc,nonumberlist=true]
\end{document}

I'm redefining \glossaryentryfield because of a special style I need to have, including the capitalization of the first letter of the description. That stuff works with the long style, but stops working with the longragged style (see the commented line).

LaTeX (pdflatex) complains

! Extra alignment tab has been changed to \cr.

when processing the .acr file generated by makeglossaries.

I'm kind of stuck with that problem since I'm unable to identify the reason. Any ideas?

longragged uses \raggedright, which redefines \\ and this means that you can't use \\ to end a tabular line. Use \tabularnewline instead:

\\newglossarystyle{longraggeduc}{%
%  \glossarystyle{long}%  <-- works
  \glossarystyle{longragged}%  <-- does not work
  \renewcommand*\glossaryentryfield[5]{%
    \glstarget{##1}{##2} & \makefirstuc{##4}##3\glspostdescription\space##5\tabularnewline
  }
}
