I am using Disconnected IMAP account to MS Exchange 2003 server. I was in inbox on regular e-mail (not from mailing list) and I have selected Folder -> Mailing List Management... and kmail crashed with the following stack trace. This problem seems to be reproducable.

Application: KMail (kmail), signal SIGSEGV
