Bug 251280

Application: kmail (2.0.89)
KDE Platform Version: 4.5.68 (4.6 >= 20100912) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-gentoo-r5 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Adding a favorite folder while the contents of that folder was being populated (might have been the first time the folder was shown)

- Custom settings of the application:
QSQLITE3 akonadi backend as it's the default in Gentoo nowdays.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
