Comment 1 Rex Dieter 2012-09-27 15:59:24 UTC 
reproducible with qt-4.8.2 too, so we can probably discount any blame on qt-4.8.3
Comment 2 Myriam Schweingruber 2012-10-11 10:45:43 UTC 
Shouldn't this be assigned to solid?

New crash information added by DrKonqi

krunner (0.1) on KDE Platform 4.9.5 using Qt 4.8.4

- What I was doing when the application crashed:

Just launched Krrunner, and tried to start an app.
By the backtraces it looks the same bug as reported... although this is the first time it happens on my system.

krunner (0.1) on KDE Platform 4.10.00 using Qt 4.8.4

- What I was doing when the application crashed:

I was simply typing a search term in krunner.

I am only adding this to tell that the bug still exists in 4.10

Comment 8 Jacopo De Simoi 2013-02-13 13:59:53 UTC 
This could be fixed by 06c934efdcdf3a8bb18982f53f9abcf2c67049d0 (in 4.10git and master)
Basically, the runner was accessing the device from another thread, which can cause unexpected issues. 

Could anybody please check? If this is the case, I could backport to 4.9…
Thanks
Comment 9 Lukáš Tinkl 2013-02-15 12:32:26 UTC 
Rex, did you have time to verify this?
Comment 10 Rex Dieter 2013-02-15 15:44:32 UTC 
Interestingly, seems I had this krunner plugin enabled already on my unpatched 4.10.0, and hadn't experienced any related crashes.

Unfortunately, that doesn't help explain the crash reported against 4.10.0 in comment #7

I tested with the aforementioned kde-workspace patch too, and no crash/regressions either.

my laptop doesn't currently have any "removable devices", so let me put my cd/dvd drive back, and see if that makes any difference...
Comment 11 Rex Dieter 2013-02-15 16:30:08 UTC 
no problems after adding drive with or without media in it now (patched).  Let's go with this being fixed.  thanks all.
