Sentry Crash Report:

Description Javier O. Cordero Pérez (Cuperino) 2018-08-28 04:14:24 UTC 
Application: plasmashell (5.13.4)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.14.60-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I disabled and enabled Wiireless continuosly after I noticed the following unusual behavior...
- Unusual behavior I noticed:
I was connected to a network. I disabled wireless without disconnecting from the network. When I re-enable wireless after this, the network no longer shows despite the fact it's broadcasting its SSID. When I disable wireless again, all other networks go away and for an instant I can read the name of the network and the word 'Connecting'.

In case it's usefull in any way, I use the KDE Wallet to manage the password for the network in question.

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