Application: baloo_file (5.18.0)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-49-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
System booted up: OK. Problems begin as soon as I log-in to KDE5

- Unusual behavior I noticed:
Heavy IO load (HDD) and 100% CPU taken by baloo_file_extractor.
.xsession-errors getting bigger and bigger.
Loggin in as another user everything seems to work fine.

- Custom settings of the application:
 To be able to work I have to kill (15) baloo_file_extractor.
The problem begun (as far as I can remember) when the system sopped to ask me for the luks password to decrypt the swap partition.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
