Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.5 (KDE 4.3.5) "release 4"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Crash occurs each time I check a dIMAP email account after restarting the laptop after suspend to disk. 
When checking the dIMAP email account immediately after re-awakening the system and immediately cancelling the process of checking the dIMAP server, no crash occurs.
 
A second attempt to check the dIMAP server is successful then.

Only when forgetting to check and cancel the check of my dIMAP account immediately after re-awakening then after about 5 minutes the message about the inability to connect to the dIMAP server pops up.
When closing the pop-up message, kmail crashes.
