Version:           1.9.3 (using KDE KDE 3.5.3)
Installed from:    Ubuntu Packages

I am testing Riddell's KDE 3.5.3 package for Kubuntu Dapper:
deb http://kubuntu.org/packages/kde-353 dapper main

I am using Disconnected IMAP with MS Exchange Server 2003.

I have right-clicked on trash folder (Deleted Items on Exchange server) and Empty Trash did crash Kontact application (see backtrace attached). 
When I have restarted Kontact, messages were still in trash folder and Empty Trash did not crash this time.
Note: before the crash, I have deleted (moved to trash) multiple (50 or so) messages from one folder (also IMAP). It may be related to trash.
