 i'm using pidgin 2.2.0 on fedora core 6.

 since pidgin/gaim 2beta i've been getting crashes occasionally when
 closing a conversation. it can be a single tab or the last tab and
 therefore the whole window. it /may/ only be irc chats since i can't
 recall it crashing when closing an msn conversation, but can be PM or chat
 in irc. it doesn't have anything to do with how much content is in the
 window -- i've had the crash when closing a single line of text before as
 well as chats which have been open in a busy channel all night.

 since 2.1.1 and now with 2.2.0 the crash has been occurring much more
 frequently. i get several a day, but i can't reproduce on demand.

 running pidgin from a terminal showed me that it is a segmentation fault.

 i've tried to follow the instructions on the wiki to produce a backtrace
 but am having problems with gdb. i run gdb pidgin, followed by handle
 SIGPIPE nostop and run. pidgin loads but then before long (one irc network
 has connected and a couple of "welcome" conversations have opened)
 freezes. gdb has the following output:
