Description Robin Laing 2015-09-16 03:49:12 UTC 
Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.6-201.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Possibly related to bug 349289.  Bug reporter wouldn't let me select it.

I was adding applets to my desktop.  In the case of the crash, I had added Memory Status and accidently installed 2 copies.  I went to remove one and accidently dragged it to a different virtual desktop.

Tried it again and got a second crash while writing up this report.

Panel configured for auto hide.  Not full width.

Third attempt, crash only seems to occur if I drag under the panel, not to any sides.

Widget appeared in the panel.  Tried with Network monitor but there was no problem.  Once I started to download the updates, the Network monitor also caused a plasma crash.

Related to widget data being updated so crashes only occur with widgets that have data changing?

Memory usage and CPU load both are constantly changing.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
