Bug 375384

Application: baloo_file_extractor (5.29.0)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.4-201.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

-- 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
Using host libthread_db library "/lib64/libthread_db.so.1".
