Bug 309708

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.80
Qt Version: 4.8.4
Operating System: Linux 3.7.0-0-generic i686
Distribution: Ubuntu 12.10

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

hello!

my name is simon. i use kubuntu 12.10, with raring proposed environemnt enabled and desktop system called project neon. in there you have an option to turn on GRID DESKTOP and in there you can specify tho use slideshow of pictures (scaled & cropped). After i set that up, also i put a few widgets (one system monitor, one rssnow, 2x analog clock, 2x weather forecast, one floder view and one calendar) on the desktop workspace and also added one emptpy panel on the left.

then i rebooted the computer. when the desktop again showed, it had the empty panel and the main panel, but ALL widgets were gone any my desktop again is default desktop with default picture not slideshow.

and dr. konqi also appeared with saying that there was error. so im sending this error report

nice day!

simon :)

The crash can be reproduced every time.
