Bug 319965

Application: plasma-desktop (4.10.60)
KDE Platform Version: 4.10.60
Qt Version: 4.8.5
Operating System: Linux 3.9.0-2-generic i686
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Every time i restart project neon - this always happened since i started using project neon - after reboot (even from clean install) the desktop preferences (such as grid desktop, slideshow, choosing the wallpaper/s) and desktop widgets are reset to default.
Problem is sometimes after not reseting the computer for a week or two finally it starts t o work normally...but this time (i use saucy) still every time is the same...

i tried to make bots folders ".project-neon-de" and ".kde" and all files / folders inside to be unlocked for editing (so de-rooted them), but it doesnt help.


This time after reboot also this window dr. konqi for crash report appeared.  with this particular error it didnt restart yet... but its also true that computer before reset hanged - i was updating it via aptitude in konsole and it came to "reconfiguring font cache"... at the same time i tried to pull one widget on the desktop but when i clicked on add widgets from kickoff menu (+add widgets) the window slowly appeared and then froze without displaying any icons fror widgets..


at the same time i had firefox nightly, ktorrent, amule, 2 dolphins, konsole also opened...

hope it helps

thank you!

nice day : )

Simon
