I was dragging some widget application (mio, qalculate - I could not remember exactly) to plasma panel, then the plasma desktop crash. I thought It will be fine again if I restart the desktop. However when I restart the desktop, the plasma-desktop immediately crash upon login (Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault)
I tried googling to find solution, but the problem persist. What I have tried so far
- removing ~/.kde4/share/apps/plasma and ~/.kde4/share/apps/kded
- removing ~/.kde4/share/config/plasma-desktop-appletsrc
- removing ~/.kde4/socket-linux-9lji/kdeinit4__0
Other suggested that downgrading the Qt4* solved the problem. I cannot do this, because I don’t know how to do it without Yast.
It would be great if anyone kind enough to help me, because I am new to linux/opensuse and still not accustomed to terminal.
The code below is from the Developer Information tab
