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 i686 Distribution: Ubuntu 14.04 LTS -- Information about the crash: - right click on system tray - choose "System Tray Settings" - in the "Display" section check "Manage Print Jobs" - click "Apply" - plasma desktop crashes To be able to start plasma desktop again I have to edit the "plasma-desktop-appletsrc" file and remove the "org.kde.printmanager" plugin entry. The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
