Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
Sorry, I do not know much English.
   I downloaded the file to the server. When half loaded, I clicked on the notification area and tried to move  window  with progress bar to desktop. Window moved, but a second blackened desktop, plasma generated an error and close all applications.
   Before that, I checked several times to download and everything was normal.
   Sorry if duplicate (such errors is due to some other reason).

The crash does not seem to be reproducible.
