Comment(by liuyubao):

 Debian squeeze, pidgin 2.7.2-1 crashes very frequently.

 Here is a patch against pidgin-2.7.2-1, it seems to have fixed the problem
 (I'm not sure
 because there are many cancel/destroy without setting the pointers to NULL
 in
 libpurple/protocols/msn/directconn.c).

 I checked official pidgin-2.7.3, it should have this bug too.

 I guess the cause is twice calls to purple_network_listen_cancel() by
 msn_dc_destroy() and msn_dc_incoming_connection_timeout_cb().
