Bug 337677

Application: plasma-desktop (4.11.9)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.11.10-17-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
* Copying files (by dolphin) from my hard disk to a USB 3.0 external drive
* Uploading opensuse 13.1 64bit DVD with Ktorrent
* Sending to trash (by dolphin) the files already copied to the USB drive 
- Unusual behavior I noticed:
* I have an i3-3220 CPU, the 4 cores were working at 100% or close too
* Sending to trash was pending to the copy to USB drive action to be completed
* Upload speed decreased a lot during all of that
* wallpaper image disappeared when plasma crashed

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
