Sentry Crash Report:

Description David P. 2017-05-12 16:17:04 UTC 
Application: plasmashell (5.9.5)
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.9-gnu-1-pck x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Nothing special, just some work and the usual stuff spected in a normal user

- Unusual behavior I noticed:
For some reason, the pannel stopped working and disappeared, and then reappeared, and then in the message error it sais that there was a problem with plasma shell, but I didn't care, then I restarted my session and the problem repeated but with a more comprehensive log, so I decided to report it.

Distro: Parabola GNU/Linux-libre (based on Arch Linux)
Architecture: x64

The crash can be reproduced sometimes.

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