Comment 8 Dave Plater 2011-01-29 14:21:52 UTC 
The strange behavior I reported was due to a samba share I have mounted and the server it was mounted from being shut down.

My original report:
Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.1
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
My desktop system was "sticking" and I noticed the openSUSE update applet was
displaying signs of activity, I hovered my mouse pointer over it and tooltip
reported a dbus error. I right clicked and selected quit on the context menu,
hoping that I had at last found the cause of the freezing "kickoff application
launcher" and the crash occurred.

- Unusual behavior I noticed:
Since update to kde 4.5.95 I've had an intermittent frozen "kickoff application
launcher". It freezes up  after clicking on it's panel icon when it appears and
the entire panel becomes unusable for about 30 to 40 seconds. This usually
happens around midnight and continues until I restart x or logout/login. A
kded, sometimes a couple of them, I don't know if there's supposed to be more
than one running (I can't see any atm needed to complete this report), runs at
45% plus cpu usage. Also a knotify hogs cpu. I would appreciate some direction
to find the cause.
Comment 9 Dave Plater 2011-01-29 14:24:21 UTC 
I'm now on 4.6 and I'll let you know if it happens again but 4.6 is working well with non of the irritating slow downs since the beta stage.
