So this release candidate adresses a couple of minor issues of which the most annoying was introduced in last rc.
- Bogus json decode messages introduced with RC6 newer json decoder. Those error messages weren't a stopper, but annoying
- Missing on the fly output in GUI introduced with RC5
- Fixed repo unlocking didn't work since it first checked if repo is locked
- Fixed error message propagation to json output didn't work properly
- Improve housekeeping error messages
