KDE crashes immediately on start-up, every time. I can think of nothing special I have done on the machine that could have generated this bug. I've tried logging in using the "failsafe" option in KDM, and get the same result. The initial error message is of the form "Executable: plasma-desktop PID: 1145 Signal: Segmentation fault (11) Time: 22/08/2013 23:10:35" Reproducible: Always Steps to Reproduce: 1. Start machine 2. Log in Actual Results: There's an error message which says that the Plasma Desktop Shell has crashed. I can open applications from the command line, but the background to all applications is a black screen. Expected Results: Produce the usual KDE screen.
> The initial error message is of the form "Executable: plasma-desktop PID: 1145 Signal: Segmentation fault (11) Time: 22/08/2013 23:10:35" I assume you get that message from a dialog (known as Dr.Konqi) which show up after the crash ? Then please provide the backtrace which you can get from the second tab of that dialog .
Sure. I got that backtrace but with a message saying that it would not be useful in tracing the bug... but I can get it again. (This evening, when I'm back home). I think I was inexact. Sorry. Really, it's the Plasma Desktop Shell crashing, rather than KDE as a whole. I can open individual applications from the command line, and they "look all right".
This is the backtrace. From what I can understand it's not informative as it stands, and I have to install more software in order to get an informative backtrace. Is that so? If so, I'll get on to it as soon as I can clear some time. In the meantime I've tried one fix I found on the web: deleting a kde cache which might be corrupted. http://forum.kde.org/viewtopic.php?f=67&t=101326#p219323 That doesn't work in this case. So, here's the backtrace. Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

I had same problem. I did: rm -r ~/.kde4/share/config/plasma* When I logged back into KDE it reported another crash but continued working. It now works fine except I cannot add any programs to the quicklaunch (or it will crash)
Hi, It's not resolved. I've updated all the packages on my machine, and done rm -r ~/.kde4/share/config/plasma* but the bug is still there, unchanged.
Probably fixed with this commit: http://commits.kde.org/kde-workspace/af6653c766981ca81bac499de284abcdc2c7f08f *** This bug has been marked as a duplicate of bug 322283 ***
