Tradfri not working after update to OH2.2

I updated from OH2.1 to OH2.2 on openhabian a few hours ago. Now Tradfri isn’t reliable working for me. After a reboot it seems to work but if I have to change something on the things file and save I get this and I can’t switch my bulbs.

Disconnect the Item*s from the Tradfri Bulbs und reconnect… that should fix the Problem …

I think the Problem is related to this Issue …

That worked. Thank you.
