I tried but it's only little help. It can associate exactly once in the
beginning. Further attempts to change associate to another AP or SSID
bring the same error again.

At least the weird communication problem with nm-applet does not come
anymore, that part seems to work ok now.

Eduard.

I cherry-picked various fixes in 1.4.0-4, could you please check if you
are still affected by this problem with this version?
If so, it probably would make sense to take this upstream.

Right, right.

Interesting, it partly helps! I can select hotspots with nmcli now and
it seems to be ok so far.

However, now nm-applet does not work anymore. I tried to investigate
strace output and couldn't see the reason. It simply shuts down and
exits shortly after some dbus communication. I tried to trace that
communication but the results are inconclusive (at least IMHO):

Could you add

[device]
wifi.scan-rand-mac-address=no

to your NetworkManager.conf and see if that changes anything.

This smells like [1]
