Comment 1 Hussam Al-Tayeb 2012-12-26 20:53:28 UTC 
after the freeze, I don't get a crash report menu. eventually plasma-desktop just disappears. and I have to run plasma-desktop from konsole again.
Comment 2 Jekyll Wu 2012-12-26 21:22:14 UTC 
When it happens, run "gdb -p `pidof plasma-desktop`" in konsole, then run "bt" and get the backtrace.
Comment 3 Hussam Al-Tayeb 2012-12-26 21:59:24 UTC 
I can't. the whole desktop freezes. I can't even select other windows. and if I ctrl+alt+f1, plasma-desktop instantly dies.

Comment 7 Martin Flöser 2013-06-04 14:43:23 UTC 
the backtrace is lacking debug symbols, so we cannot see where in the code it's happening. If you are still able to reproduce please do the steps again but with proper debug symbols.
Comment 8 Hussam Al-Tayeb 2013-06-04 14:45:02 UTC 
it doesn't happen anymore so I will just close the bug.
