Application: kmail (2.0.89)
KDE Platform Version: 4.5.67 (4.6 >= 20100901) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.34-gentoo-r2 x86_64
Distribution: "Gentoo Base System release 1.12.13"

-- Information about the crash:
- What I was doing when the application crashed:

adding a folder from an IMAP account (gmail account to be specific) to the favorites.  The folder is in favorites when I restart KMail, it just crashes when added.

The crash can be reproduced every time.

-- Backtrace:
