Version-Release number of selected component (if applicable):
kdepim-3.5.0-0.2.fc4

How reproducible:
Always

Steps to Reproduce:
1. Go to the Trash folder from an IMAP account
2. Right-click and select "Empty trash" from the context menu
3.
  

Actual Results:  Kontact/kmail crashed (after all the e-mails in Trash shortly appeared crossed out). On restarting Kontact, all e-mails are still present.

Expected Results:  The Trash folder should have been emptied.

Additional info:

I've recompiled kdepim myself, since I need gpgsm support through gpgme. I've used gcc-4.0.2-8.fc4 to compile kdepim.
