pidgin crashed with SIGSEGV in pidgin_conv_window_add_gtkconv()

[GonzO]

Double-clicking on a contact's name opened a new window, and made blank the contents of the old.

Pidgin crashed soon after.

I think this may be related to 474211, but that one was last heard from in Maverick, and didn't have nearly the crash reporting files that I do.
