Michal Čihař - I did it again

I did it again

It happens too often in recent program releases - I do a release and few moments after it I notice some quite important bug. Today it is deadlock in upgrading in Ukolovnik. I should have seen it before (as I fixed simmilar problem for another part of config layer), but I haven't.

I'll wait for some time if something else appears and then make another new release. You can meanwhile apply patch from the bug manually or use daily snapshot.
