starts

--------------------------+-------------------------------------------------
 On Red Hat Enterprise 4 (2.6.9-55.0.9.ELsmp x86_64), I've noticed that an
 open conversation window will suddenly vanish when I'm not using pidgin at
 all.  I installed the debuginfo RPM and started pidgin with coredumpsize
 unlimited, and caught a core dump:

 In frame 4,
 {{{
 *conv = {type = PURPLE_CONV_TYPE_IM, account = 0x647980,
   name = 0xab5540 "gwcharlwood", title = 0xc4eff0 "William Charlwood",
   logging = 1, logs = 0xc82830, u = {im = 0xc1e6d0, chat = 0xc1e6d0,
     misc = 0xc1e6d0}, ui_ops = 0x5cdd00, ui_data = 0x0, data = 0xc8b130,
   features = 67}
 }}}

 The crash is caused by dereferencing gtkconv (which gets its value from
 conv->ui_data).
