-- Information about the crash:
- What I was doing when the application crashed:
i deleted all of my postboxes to set them up anew. i also deleted my identities (2) to reconfigure them. after that i applied the changes and kmail reported me, that the home-postbox-folders and my googlemail-folders of the account can't be found anymore.
kmail reported also, that the imap folders (/home/.kde/blablabla) of my profil can't be found anymore.
after klicking about 10 times the ok-buttons of the appearing windows, kmail crashed.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
