This bug affected me after editing the latex plugin preferences as super user, in Ubuntu.

Found a fix in https://bugs.launchpad.net/ubuntu/+source/gedit-latex-plugin/+bug/957924

Follow these steps
1. Remove some config files as explained here: https://bugs.launchpad.net/ubuntu/+source/gedit-latex-plugin/+bug/957924/comments/10
2. then upgrade gedit-latex-plugin to version 3.4.1-1. I got it from http://packages.ubuntu.com/quantal/all/gedit-latex-plugin/download and installed in Ubuntu 12.04.

Works for me.
