Sentry Crash Report:

Description tuxtoriel 2017-03-01 16:38:20 UTC 
Application: plasmashell (5.9.2)

Qt Version: 5.8.0
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Browsing the web normaly. Nothing special. It already happend a day ago, with no special context too.

- Unusual behavior I noticed:
I use the clipboards Action system. Since I saw someone complain about the fact that the "Enable MIME-based actions" checkbox is useless, since it always enables them (regardless of the state of the checkbox).
So, using this feature, I disabled it, wanting to see if I have the bug too or not. And indeed, the unchecked checkbox does not disable the MIME-based actions. I tried with a restart, but nothing changed.

Since This restart, regardless of whether I turned the Actions popup on or off (globally), it turns itself on at each restart (And, as before, MIME is always on).

And, to the final point, Since the aforementionned restart, Plasma crashes randomly.

It might just be a coincidence, but since it matches chonologically and since the clipboard is managed by Plasma, there could be a link.

- Custom settings of the application:

Turned clipboard "Enable MIME-based actions" off and later back on (the button doesn't seem to work).

The crash can be reproduced sometimes.

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

I don't think it's related with the clipboard, but it would need a more detailed backtrace.

please report the klipper bug separatedly, under the klipper component
