A bug present in pidgin (http://developer.pidgin.im/ticket/8155) is still present in Carrier(fun?) Pidgin. Sending an offline message after a period of delay will cause Carrier to crash, but bizarrely further messages AFTER the crash will not cause one. There seems to be a definite causality between the time Carrier has been online and whether or not sending an offline message will cause a crash. In my experience, a crash is 100% assured after a period of greater than 1-2 hours, and prior to that will happen entirely at random. Versions of Carrier 2.5.5 to 2.6.1 are effected (I do not know about previous versions).
