As far as I can tell, libpurple removes the timeout at the right time; there's no code path that can let haze's idle callback fire before libpurple's one has either run or been cancelled. So I can't see why this would happen, and I can't reproduce it any more.

If you supply incorrect credentials haze crashes on connection, every time.

Shortly after

(haze:20176): tp-glib-DEBUG: tp_base_connection_change_status: was 1, now 2, for reason 3
** (haze:20176): DEBUG: haze_im_channel_factory_iface_close_all: closing im channels
(haze:20176): tp-glib-DEBUG: tp_base_connection_change_status: emitting status-changed to 2, for reason 3

** Message: [info] connection: Disconnecting connection 0x9265588
** Message: [info] connection: Destroying connection 0x9265588

you dereference freed memory of some form, usually because the prpl is inspecting its info stored on the connection after it's destroyed.

Thank you for your bug report. Do you still experience this issue with an up-to-date system?

Yes, it appears to still occasionally crash. Worse, if it crashes, Empathy will not display any messages. I had a conversation where the other party was responding to me, but I wasn't receiving their messages at all. This is with Pidgin 2.4.3. If the work-around for AIM is to use libpurple, perhaps the integration needs to be more robust and gracefully recover from such issues.

This and other bugs (#212662, #214478, #217842, #218816) seem to be caused because of double free from purple_account_disconnect called twice. The issue is a telepathy-haze one. The upstream bug https://bugs.freedesktop.org/show_bug.cgi?id=14933 is fixed and released as part of 0.2.1 release.
