-- Information about the crash:
- What I was doing when the application crashed:  Logged into KDE after boot up, baloo file extractor crash notification.  Happens every time after booting.  If restart is selected from crash report baloo file extractors consumes all available system memory after about 10 minutes (16Gb).  Memory usage reported by ksysguard.  If not restarted process baloo_file_extractor shows status of 'stopped'.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
