Summary: Plasma crashes when deleting a second system tray in
the Desktop
Product: kde
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: unassigned-bugs at kde.org
ReportedBy: andresbajotierra at gmail.com
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.71 (KDE 4.2.71 (KDE 4.3 >= 20090428))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686
Distribution: "(none)"
What I was doing when the application crashed:
Qt: 4.5.1 (qt-copy 958974)
kdelibs svn rev. 963904 / kdebase svn rev. 963904
extragear/libs/libknotificationitem svn rev.963899
(I have installed libknotificationitem from extragear/libs), Kmix is the only
currently running application which is using it at my system here.
Steps to reproduce:
- Revert plasma configuration to defaults if you want
- Run plasma-desktop
- Once it is finished, add a second system tray in the desktop
- Remove it
Plasma crashes.
This bug is reproducible for me.
