Bug 193753

This is probably related to bug 189959
If you can reproduce the crash at will, may you read
http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
and post a complete backtrace here? You may need to install some debug info
packages. Thanks

I am bit busy managing my KDE4 transition. So it will take a while, if I forget, just send me a reminder. But what is missing in the above backtrace? I thought I had all debug packages installed?

No problem
The debug symbols missing are those from the "libknmstorage.so.4" file.
Thanks

I do not know if this better, because it is bit complicated to know in Kubuntu which debug-packages need to be installed for that. I could not find any related debug-info, so installed anything I could find.
