Application: kmail (4.8 pre)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH x86_64

-- Information about the crash:
I've started kmail 2 with a clean config the first time and tried to remove the "local folders" resource, thinking that I don't need it.

well, it crashed kmail and the mail dispatcher agent with pretty much the same backtrace.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
