Error on opening

[bbhtt]

I can see the following log coming from OLA while running the flatpak:

Not sure if they break some functionality.

The bit about missing devices under /dev/* can be ignored I think OpenLightingProject/ola#513. Maybe those plugins should be disabled.

Disabling the openmdx and karate plugin fixes the warning.

Ok for warnings (we'll see that in #14)

For the Traceback, it's due to the version of ola embedded in the flatpak and the latest versions of python. This issue has been fixed (OpenLightingProject/ola#1690) but there has been no release since.
I don't really know what we can do...

Thanks! I think we can safely ignore it for the time being.
