Hmm, I think this one is a different bug after all.

Still valid in a current SVN version

Still valid in a current SVN version, also on Windows.

I get this crash at least couple of times per day if I use Disconnected IMAP. Did not see this when using regular IMAP (on same MS Exchange 2003 IMAP server).

I am running up-to-date KDE 4.2 from SVN. Is there anything I can do to help fix this problem?

With recent SVN, I get a bit less of crashes (one per week), but I still get some.
Mostly it looks like it is related with large operations. 
Last crash (today) happened when I did "Move all messages to Trash" on my Junk Mail folder.
After restart, Junk mail folder was empty (local dimap cache), but was filled with all e-mails after sync with IMAP server (MS Exchange 2003).

Same backtrace here (v4.1.4) when closing Kontact during send operation (disconnected IMAP).

Addition to comment #14:
I never got this crash with 4.1.2 or 4.1.3, but since the first crash yesterday on 4.1.4, I get this quite regularly now. Even if the machine is unattended and kmail is only supposed to check for mail every now and then. Argh!

I'm not able to reproduce it: on step 3 (Save mail in Draft folder on the IMAP) the mail il saved and no password are asked. Kmail is still running and there is no crash.

Cannot reproduce on KDE 4.2.2 (Kubuntu). As for FiNeX saving to the IMAP Draft folder does not ask for password, saves normally, no crash.

Thanks for double checking Martin.

We have received a report about this crash at https://launchpad.net/bugs/378232 in regards to KDE 4.2.3.
Steps to reproduce are:
* write a mail with an attachement that is greater than approx 1MB, just to ensure the sending process needs some time.
* click on send, the mail comes into the outbox, kmail/kontact starts sending.
* close Kontact WHILE sending the mail.

Oh, and it should be pointed out that in the downstream bug, the reporter said that this only happens with kontact + kmail, and not kmail on its own.

Can you ask the reporter if he's using Qt 4.5?

I think it's abug already fixed there.

The repository containing the KDE 4.2 packages also contains Qt 4.5.1 packages, so it is pretty safe to say that he is using Qt 4.5.1 since an upgrade with those repos available would upgrade both Qt and KDE.

I can still reproduce the bug with KDE 4.3.4 and  Qt4.5.3.

Thank you for your report. Kmail1 is currently unmaintained and the code has changed sufficiently in Kmail2 so the backtraces are not really useful anymore. Should you experience the same crash in Kmail 4.8.5 or later, please open a new report for Kmail2. Thank you for your understanding
