Sentry Crash Report:

Description Piotr 2015-05-29 19:44:10 UTC 
Application: krunner (4.11.11)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-53-generic x86_64
Distribution: Ubuntu 14.04.2 LTS

-- Information about the crash:
recently krunner started to crash when i use it. Just simple type: digika....crash. It worked ok till now.


What is important (well maybe) I have setup baloo to index my NAS folders. But that also worked for a long time.

The crash can be reproduced every time.

After the crash the ALT-F2 is not invoking krunner (nothing happens).

-- Backtrace:
Application: Interfejs do uruchamiania poleceń (krunner), signal: Aborted

Comment 2 Piotr 2015-05-31 11:20:58 UTC 
I vote it is baloo problem. But not sure so I leave krunner.
Comment 3 Vishesh Handa 2015-06-02 13:47:32 UTC 
Fixed with the August 2015 release of Plasma
Comment 4 Piotr 2015-06-02 15:07:18 UTC 
So it will not be fixed in Kubuntu LTS 14.04?
Comment 5 Piotr 2015-06-04 10:00:20 UTC 
How can I fix the baloo databse? It is not working now. Remove it and allow baloo to index files once again?
Comment 6 Vishesh Handa 2015-06-05 16:48:15 UTC 
$ balooctl disable
$ balooctl enable
