I fixed a bug about it in kmail-4.4.7 could you test it please ?
Regards
Comment 2 Pascal Vandeputte 2010-11-22 15:15:42 UTC 
I'm on Kmail 1.13.5 now on KDE SC 4.5.1 (Kubuntu 10.10). I still run into it from time to time, but it has become a lot harder to reproduce.

What I noticed today as well though, is that KMail reproducibly crashes with a segfault on a specific mail message containing a winmail.dat attachment. A couple of months ago I migrated my own company mail away from Exchange to Cyrus IMAP using imapsync, so all mails older than April 2010 contain such an attachment. Maybe it's related to this crash (that mail was still sitting in inbox), maybe not. Maybe imapsync did some odd conversion causing an invalid mail file.

Thunderbird and RoundCube can display the mail though, I've now moved it to an archive folder, I'll update this bug if it still occurs.
Comment 3 Myriam Schweingruber 2012-08-19 10:54:12 UTC 
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
