It seems like this is a show stopper!

After some reports on twitter, I tried it myself: I can't log into the 
backend anymore, as the page doesn't load. I suppose there's some 
deadlock or infinite waiting to get a lock.

My settings for lock are all the default ones.

I hope this can be fixed ASAP and trigger release of RC3.

Kind regards
Steffen
