Since I don't have enough time to look into this, I've just sent a 
revert. I've looked couple of times at the code, but unfortunately 
solution didn't come up

You should be in CC list, can you also test and reply to patch with 
Tested-by: tag, which will indicate, that revert actually works for you

Thanks
