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

I noticed nepomukstorage had repeatedly crashed. To investigate, I launched in from the console: 

nepomukservicestub nepomukstorage

This caused the mail indexer to crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Nepomuk Feeder (akonadi_nepomuk_feeder), signal: Segmentation fault
