*** KMail got signal 6 (Crashing)
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kontact path = <unknown> pid = 6094

Kdbg provide a useless backtrace :
Application: Kontact (kontact), signal: Aborted
[Current thread is 0 (process 6094)]

Version-Release number of selected component (if applicable):
kdepim4-4.2.90-1mdv2010.0.src.rpm

How reproducible:
On first fetch (automatic every 5 min autofetch)

Steps to Reproduce:
1. Get a free.fr zimbra account
2. Setup a disconnected imap account in kmail (started in kontact)
3. Let it automatic fetch the mails
