Please read the following page and provide a backtrace for this crash : http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

I just tried this two times, one having kmail closed before using krunner and one having kmail open. In both cases, the mail was sent successfully and there were no crashes.

Try doing it with an imap account where the sent mails must me moved to the remote server.

The backtrace is very similar to the one in bug 171002. (dup?)

The problem looks like the use of an static (but empty) list of windows.

Could this bug be confirmed?
I can reproduce it everytime i want.

Are you able to test it with a more recent kmail version (like 1.10.3 or 1.10.4?). There have been a lot of changes and bugfixes between that versions.
If you are still able to reproduce it at will with that version, then it will marked as new.

I have KMail: 1.11.0 and the bug is still there.

It's most probably a dupe of bug 171002, but I am not sure, so let's forward this to the kmail developers...

*** Bug 171002 has been marked as a duplicate of this bug. ***

Ha!  I just tried to commit the same fix for bug 171002 (which has a simliar backtrace, and crashes on the same assertion), but it conflicted with your commit.  It fixes that bug just fine, by the way.
