The broken code is in reportbug. Reassigning back. This bug is a case of broken code being exposed by a bug fix elsewhere. Reportbug was trying to use sys.exit() to exit the program, which does not work reliably when threading is involved as in the GTK UI. Due to a bug in python it had only appeared to work.
