For a released stable dist, a crash in glibc (memory management) always has the bad smell of something corrupting the heap, and in this case, it's related to IMAP access again,

and

apply. It's a weak spot of Claws Mail. I haven't found the time to continue with debugging http://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=2769
Comment 6 Raphael Groner 2014-03-06 12:28:27 UTC 
Thanks for your debugging. I have the impression that the crash happens when the connection dies unexpectedly, maybe while the process of scanning for new mails.
Comment 7 Michael Schwendt 2014-05-01 14:41:03 UTC 
Recently, there have been several bug-fixes upstream that will stop some of the side-effect based crashes in e.g. memory management.


This bug will need retesting once a new version of Claws Mail (or a Test Update) will be available.

I think, I've found a process to reproduce:
While Claws-Mail is checking for new mails and the network connection is very slow (or not working at all), it doesn't detect a disconnection or reconnection. It waits then forever and crashes finally at some point. The systray icon doesn't show the disconnection state while that happens, probably cause it doesn't get notification from glib. So I guess Claws-Mail tries to use old invalid parameters (cause not aware of a reconnection) when the new connection is established.

There's no crash when I unplug the network while Claws-Mail is checking for new mails. Thanks.
