Version:           Version 1.2.4 (enterprise 0.20070907.709405) (using KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

I checked the box Enable IMAP resource functionality. Due I have no CachedImap I chose the Standard(Ical/Vcard) format. I chose a folder of one of my IMAP-account.

When I click on apply or ok, Kontact (kmail) crashes. I can reproduce it 100%.

It doesn't matter which account and folder i choose.

Traceback:
