Comment 2 for bug 881175

Ok, I tried to reproduce this with my IMAP account in a natty VM a bit. I can fetch, read and remove emails fine, but thanks to the famous "missing resource collection" error I couldn't send something or check the settings so I need to fix that first before trying to reproduce this.

What you could do would be to enable kmail debug output in kdebugdialog and then check ~/.xsession-errors for anything useful when you hit the issue.
