When I close kontact, it crashes. When I close any of the components (kmail, akregator, korganizer, ktimetracker) this doesn't happen.

Running kde 4.1.4 on kubuntu

backtrace:

Application: Kontact (kontact), signal SIGSEGV

ps. there are a few other mouse-clicks in kdepim that cause crashes, such as file-edit-history in ktimetracker (bug 182876)
