Summary: Crash in plasma applet task manager related to grid
layout
Product: plasma
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: plasma-bugs@kde.org
ReportedBy: octavian.voicu@gmail.com
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic x86_64
Distribution: Ubuntu 9.04
What I was doing when the application crashed:
Crash occured when I clicked 1-2 photos multiple times in rapid succession in
Dolphin, in a remote smb folder. This generated a series of events such as
notifications (file coping via smb), new taskbar buttons and regrouping of
taskbar items (the multiple Gwenview windows that were opened), so it's hard to
pinpoint the exact cause. Also, I wasn't able to reproduce this in this manner.
I'm guessing this particular crash is related to the automatic arrangement of
items inside the grid layout used in the task manager.
