The synaptic bug might be a different problem. To attach a light crash file you can install libglib2.0-0-dbg libgtk2.0-0-dbg synaptic-dbgsym and run apport-retrace -c file.crash, it'll update it with a debug backtrace and drop the dump
-- GTK applications crash sometime with gdk_events functions to the backtrace https://launchpad.net/bugs/71345 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
