Description Stefan Krüger 2017-05-10 14:33:08 UTC 
Application: krunner (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-51-generic x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
in about 50% of the cases i start krunner with ALT + Spacebar it crashes instantly or if i start typing.
could this be related to a slow disc access?

The crash can be reproduced sometimes.

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

Comment 2 Christoph Feck 2017-09-07 22:00:52 UTC 
Not a duplicate, the backtraces are not related.

If this is reproducible, a valgrind log would help to debug this memory corruption.
Comment 3 Stefan Krüger 2017-10-09 20:27:28 UTC 
@(In reply to Christoph Feck from comment #2)

i have update my system to 17.04 some time ago.
currently i can not reproduce this behavior.
so eventually we could just close this?
if it helps - i think i have a backup image/disc of the old system some where - i could try to put it back in and check if i can reproduce it then. do you have a good tutorial / getting-started information on valgrind logs? (i currently don't know what it is / how to perform this kind of logs..)
Comment 4 Nate Graham 2017-10-09 20:37:09 UTC 
That's good, it's probably fixed now. A lot of KRunner crashing bugs have been fixed since Ubuntu 16.10 was packaged.
