Comment (by cjr):

 Hi Ethan,

 I am trying to get information on myself there.  I tried to wait until I
 was completely logged in, and ran into another problem. I get my jabber
 account disconnected with a "Stream Error" reported by a popup dialog, and
 choosing to re-connect promptly segfaults Pidgin, still in free () libc,
 but this time there is the "No symbol table info available." message like
 in #839.

 Below is the backtrace, and here is the
 [http://thaiopensource.org/~chris/pidgin3.ogg .ogg] of myself generating
 the problem.
