Bug 83259 – Gaim crashes when using the MSN protocol. It seems to happen shortly after closing a conversation window

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Dion Sole 2005-02-24 21:17:50 UTC]

Gaim gets an out-of-bounds error on occasions when using the MSN protocol. It never occurs when a conversation window is open, and as far as I can tell, it occurs most frequently about one minute after closing a conversation window.
I looked into it with gdb, and have found that the crash occurs during the gaim_find_prpl() function of prpl.c at line 45. gaim_find_prpl() gets passed an argument of type GaimAccount->protocol_id, which is returned by the gaim_account_get_protocol_id() function. This function returns an outofbounds memory address as the protocol id. 
Interestingly, this is called from a function that sends the message "The conversation has become inactive and has timed out" to the conversation window. But this window is no longer open, so that may have something to do with it. 
My gdb knowledge is rather lacking, this is the first time Ive used it :P, so I cant find much more yet. Please tell me what other info you might need, as I still have the core file sitting around.

[Comment 4 Dion Sole 2005-02-25 02:03:26 UTC]

Ive just noticed gaim-1.1.4 is out. Ill use that, and post here if the same error occurs with that version too.

[Comment 5 Dion Sole 2005-03-24 18:47:04 UTC]

I havn't noticed this at all with latter Gaim versions, so I think this could be safely marked Fixed
