            Bug ID: 372725
           Summary: baloo_file_extractor taking 100% CPU and IO at login
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: carlo.tognetti at europe.com
  Target Milestone: ---

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
