Description Steffen Möller 2011-01-03 09:30:45 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.37-rc5-amd64 x86_64
Distribution: Debian GNU/Linux 6.0 (squeeze)

-- Information about the crash:
Hello,

I have this latest version of KDE on Debian unstable running and that bug reported to be fixed apparently is not. Well, the trace looks slightly different, but the symptom is much the same. I do not recall to have typed enter. I tend to think that this bug is not yet fixed - or at least not in my 4.4.5.

What is possibly special is that the internet connection was not automatically opened but I had only a few seconds earlier run the sequence

sudo ifup eth0 (via dhcp)
sudo apt-get update

and ran the ALT-F2 in parallel with that apt-get update not yet completed.

skype was not yet up and possibly the one or other KDE demon also waited for something, still, I/O load was high because of the apt-get update. Kopete is installed but offline.

Good luck!

SM

Comment 1 Matthias Fuchs 2011-01-16 17:12:57 UTC 
"and that bug reported to be fixed apparently is not" --> could you please mention the bug (including the number) you are talking about?
Comment 2 Steffen Möller 2011-01-16 17:22:31 UTC 
That information was at the bottom in the automatically created part of the report. I was referring to https://bugs.kde.org/show_bug.cgi?id=224212

I have not experienced the problem again and although booting into KDE daily, I had not seen it too often before.

Many greetings

Steffen
Comment 3 Steffen Möller 2011-01-16 17:27:09 UTC 
Ah, I just saw the "Fixed in 4.5.0" note, which most likely refers to KDE (was on the still current in Debian Sid 4.4.5) not to Qt. Seems like I should just wait for a newer KDE to arrive in unstable.
Comment 4 Matthias Fuchs 2011-01-16 17:47:57 UTC 
Yes this has been fixed already in a newer version.

If you want to have a fix in Debian you should probably report a bug on http://www.debian.org/Bugs/ 
and ask them to backport the fix discussed at https://bugs.kde.org/show_bug.cgi?id=236496 comment #11

Comment 5 Matthias Fuchs 2011-01-16 18:21:57 UTC 
Btw. you can avoid this crash if you disable the places runner.
