I have tried to get some information from mousepad through gdb when I run it as root and try to hit the "open file" option. It doesn't work because the program isn't segfaulting, it is just hanging almost as if i sent the process to the background with ctrl+z but gdb just says continuing if I try to do anything with it.

I hope I have provided all the debugging info needed. I can't see how I can provide anymore I have all the debugging symbols requested installed and I followed the instructions for backtracing exactly. I have included the valgrind logs of various reproduction methods. Can someone else just confirm this is a bug, by trying to run sudo mousepad and trying to open something. Or apt-get install mousepad and just see if mousepad segfaults when you try to open it. Also try running gedit with sudo as well, and try clicking the open button. Should hang the app. Shouldn't take much work for someone to confirm this, and when someone does I have more than enough debugging info included on this bug report.

Thanks
