I receive a meeting invitation from another Kontact, I click [Accept] in Kmail, the "select resource" dialog is shown just for a few milliseconds and then korganizer crashes. I'm using KDE 4.2beta2 with akonadi resources (automatically generated)

Application: KOrganizer (korganizer), signal SIGABRT
