Plasma sometimes crashes with no apparent reason. I was just browsing the web or anything else. The bottom panel disappears, and running `plasmashell` from a terminal suspends the process. However, I can still use applications already started, I can still use key combinations to show all windows and use krunner. Drkonqi won't start up, or at least it didn't pop a window. According to systemd journal, plasmashell just core dumped (journal here: http://paste.opensuse.org/25850665). And I've put the core dump file here: https://drive.google.com/open?id=0BxTVvcxlKZ2OdVBUYWF6bWRzNjA Reproducible: Sometimes Also I have to mention there's anothor problem of KDE which I'm not sure if it's related. The screen locker has constantly broken out of no reason ( https://plus.google.com/+黄凯哲/posts/gd1reJoaCtk ). If that can be helpful, please count it.
There should be a proper crash report dialog if/when plasma crashes which creates a backtrace. A core dump is completely useless. There's not much I can do with this, except hope someone else has also reported the same bug and that it will be fixed in a next release. Sorry
