-- Information about the crash:
- What I was doing when the application crashed:

The problem started to happen since I plugged in an extra WiFi antenna, I use two network interfaces but I don't know if that is the real source of the issue or how to provide more information about it, any help? Thanks :D.

The crash can be reproduced every time.

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