I’ve noticed this thread on the Pidgin mailing list, about Pidgin 2.5.3 crashing on exit. I’m having the same problem on two totally different computers (one XP, one Vista) with a default Pidgin install and no extra plugins. All I’m connected to is MSN and one IRC server. Since Linux Mint 6 is still using 2.5.2 I can’t say if the problem occurs in the Linux version of 2.5.3 too.
