Workaround for kFreeBSD crash in reportbug

[Jeff Epler <jepler@unpythonic.net>]

This patch lets me start reportbug's text ui.  It sidesteps the
python-gtk2 problem with readline and threads by requesting that the
readline hook be uninstalled.

However, I still believe that the problem is either in python-gtk2 or
python-gtk2's FAQ advice on how to use gtk.gdk.threads_init().
