Application: kmail (1.13.7)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.38.6-26.rc1.fc15.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I clicked on a message and instead of displaying the content, kmail crashed.  The data is stored in mbox format.  Removing the indexes (.*.index and .*.index.ids) for the folder and trying again did not correct the problem.

Is there fsck equivalent for mbox folders?

This is with a fully updated Fedora 15, 64bit

The crash can be reproduced every time.
