Had the same problem in 12.04 LTS. Initially opening the preferences of latex-pluging worked well. The problem occured first after trying to add new tools in the latex-plugin settings. I could not add anything so I tried to add the toolchain as a superuser. That did not work as well. But since then opening the preferences with normal privileges always caused a crash as decribed above. I tried to use the latex-plugin with an other ubuntu user were no crash occured.
Finally deleting the files latex.pkl and tools.xml in ~/.config/gedit/latex solved the crash problem for me -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/957924 Title: gedit crashes when opening latex-plugin preferences To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gedit-plugins/+bug/957924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
