Description genstar 2019-12-24 02:21:41 UTC 
Application: falkon (3.1.0)

Qt Version: 5.14.0
Frameworks Version: 5.65.0
Operating System: Linux 5.4.5-arch1-1 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Tried to disable the "Hello Python" extension

- Custom settings of the application:
"Hello Python"/"Hola Python" was enabled.

Adblock and GreaseMonkey were too.

Also, Falkons 2/3 of the time fails to launch, giving this in the logs:
Icon theme "Numix-Circle" not found.

(I have changed themes on KDE previously)

The crash can be reproduced every time.
