-- 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
