Comment 1 Dario Andres 2010-02-10 23:25:31 UTC

From bug 225101:
-- Information about the crash:
When typing something in the krunner search results are displayed, but when
trying to choose one of them krunner becomes unresponsive and later it crashes.
This happens very often and for different search criteria and results.

[Comment from a bug triager]
Note that the backtrace in comment 3 is a different issue: bug 222439. Regards

Comment 8 Dario Andres 2011-04-10 22:56:47 UTC

[Comment from a bug triager]
From bug 270505 (KDE SC 4.4.5):
-- Information about the crash:
I wanted to compute some expression, but I didn't start with '='. So krunner
was looking for some filenames (using nepomuk?).
krunner was not very responsive at first (looks like it needed to load
something from disk), then it crashed.

It seems that the latest duplicates are a bit old. May be the issue is already fixed in the recent releases (4.5.x and later)

Comment 13 jos poortvliet 2011-12-12 22:15:08 UTC

There haven't been any query-related crashes forever. With the 4.8 release of KRunner getting close I'm quite sure this backtrace won't help fix anything so I suggest to close the bugreport.
