Sentry Crash Report:

Description GK 2012-06-21 09:34:36 UTC

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".

Thank you for your report. Could you please install the kdeplasma-addons-dbg package and provide a new backtrace?

Thanks. I installed it.  Might sound stupid, but how can I get the
backtrace again?

Comment 3 Myriam Schweingruber 2012-06-22 15:00:20 UTC

Well, by reproducing the same steps you did past time? If it is not reproducible though we should close the report as in its current stage it is not really useful. Feel free to reopen if you can reproduce it, though.
