network-admin crashes when try to open in Gnome menu

Sorry. here is bug report.

Thanks for your bug report, it has been assigned to the team responsible for handling these kind of bugs. They may ask you to provide further debugging info on this problem.

Can you please provide a debug backtrace by following http://wiki.ubuntu.com/DebuggingProgramCrash ? This is probably a duplicate of bug 55458. Thanks.

Help.
When I get to step 2b
sudo apt-get build-dep gnome-system-tools
it tells me unable to find a source package.
I must be doing something wrong?

Figured it out. Hope this is what was wanted.
Backtrace of network-admin
gnome-system tools.
By the way, gedit doesn't come up either. I'll back-trace that tomorrow.
