Bug 334036

Application: plasma-desktop (4.11.8)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

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

Several programs were open and heavily working on an older (and slow) machine, e.g. vlc playing a video, digikam setting geo information on a couple of hundred images, mkfs formatting a 250 GB hard drive with ntfs, ...

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