Bug ID: 376451
Summary: Adding Widget to the Task Manager crash
Product: kde
Version: unspecified
Platform: unspecified
OS: FreeBSD
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: yaro...@gmail.com
Target Milestone: ---
Application: plasma-desktop (4.11.21)
KDE Platform Version: 4.14.10
Qt Version: 4.8.7
Operating System: FreeBSD 11.0-RELEASE-p1 amd64
Distribution (Platform): FreeBSD Ports
-- Information about the crash:
- What I was doing when the application crashed:
Clicked on the panel -> Panel options -> Add Widgets...
Found "Pager" and tried to move it to panel the following way.
Hold left mouse button and move cursor near Konqueror and Dolphin launchers to
find a good place.
When I move cursor over Task Manager the panel disappears and crashes.
I tried other widgets. They crash when moving over Task Manager too.
