 I got this stack trace right after moving "shponglespore at gmail.com" in my
 buddy list.  I moved out out of a group, causing a "general" group to be
 created.

 After restarting Pidgin and trying to reconnect, I got this stack trace,
 similar to those in ticket #660:

 Finally, I should point out that the URLs in this error message are
 broken:
