Sentry Crash Report:

Description Mayeul C. 2015-01-29 14:44:25 UTC 
Application: plasmashell ()

Qt Version: 5.4.0
Operating System: Linux 3.18.4-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
Always reproducible : 

- Grab a window from the taskmanager, and drag it on the virtual desktop selector.
- Wait until the workspace switches to the desired desktop
- Move your mouse, as if you wanted to place the application on this desktop's task manager
- Plasmashell crashes

This may be related to some personnal settings : 

- Cube desktop animation, 2x2 desktop grid
- Task manager configured to show only tasks of the current desktop

This may not be related : 

- Theme : breeze dark

Sorry for the '??' everywhere in the backtrace. Unfortunately, ArchLinux does not provide an
easy mean to install kf5 with debug symbols.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Reported using DrKonqi
Comment 1 Mayeul C. 2015-01-29 14:50:51 UTC 
Some notes after using DrKonqi for the first time : 
- No spell checking. I heavily use spell checking when writing in English
- DrKonqi did not select the appropriate plasmashell section by itself, not sure if intended.

Should I report these ?

I just fixed that in http://commits.kde.org/plasma-workspace/63f51b7f4fb45764ae7a77d0600c5660579e9a6b

and this looks like crash in task manager
Comment 3 Eike Hein 2015-01-29 15:17:52 UTC 
This looks a lot like the context menu crash backtraces

The bug is still present on Arch, with plasma 5.2.2. If it was a duplicate of bug 343358, it should have been fixed. Please confirm it's also present for you, it's really easy to reproduce.
