pstricks and tikz packages conflicting with other packages?

Question

Why is it that whenever I add \usepackage{pstricks} or \usepackage{tikz}, I always get the error below?

Latex Error: /usr/local/texlive/2013/texmf-dist/tex/latex/xcolor/xcolor.sty:60 TeX capacity exceeded, sorry [parameter stack size=10000].

Latex Error: /usr/local/texlive/2013/texmf-dist/tex/latex/xcolor/xcolor.sty:60 ==> Fatal error occurred, no output PDF file produced!

However, if I try to compile a document with (only) those packages in a separate file, no problem!

It seems as if these packages conflict with my existing packages (listed below).

Any ideas would be very much appreciated! Thanks a lot.

 \usepackage{graphicx}
 \usepackage{gb4e} 
 \usepackage{tipa} 
 \usepackage{setspace}
 \usepackage[T1]{fontenc}
 \usepackage{multirow}
 \usepackage{lscape}
 \usepackage{slashbox}
 \usepackage{arydshln}
 \usepackage[T1]{fontenc}
 \usepackage{float}
 \usepackage{makeidx}
 \usepackage{enumitem}

Here is the code that produces the problem (with all other text removed)

Try moving gb4e as the last called package. Moreover, you have two instances of \usepackage[T1]{fontenc}. Here's the working example:

\documentclass{article} 
\usepackage{graphicx}
\usepackage{tipa} 
\usepackage{setspace}
\usepackage[T1]{fontenc} % only one instance
\usepackage{multirow}
\usepackage{lscape}
\usepackage{slashbox}
\usepackage{arydshln}
\usepackage{float}
\usepackage{makeidx}
\usepackage{enumitem}
\usepackage{pstricks}
\usepackage{tikz}
\usepackage{gb4e} % put gb4e here

 Hello world.
