Application: krunner (0.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I open Krunner through Alt+F2. After writing a file name (or folder name) that I would like to search and open, Krunner crashes. 

I am not sure whether this is related, but often Krunner does not show desired results, although I have Nepomuk search enabled. For example a file (that is also properly tagged) cannot be found in Krunner by name nor by any of the tags.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Run Command Interface (krunner), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
