The error comes from QMLManager::openLocalThenRemote(). It fails to open 
the local git repo, but as we only get here with known credentials it 
further assumes that the PIN fase has not been passed yet (as that is 
the moment the local git repo is created). This is obviously a wrong 
assumption in your case.

There is something special in your logging. It says "0.708: 
Synchronising data file", which has a very early timestamp during the 
run. When I clear my app data, on the way you do, I land on the first 
credential page to enter my email/passwd. This is logical, as the 
settings are stored in the data as well, so entering this is needed. And 
the Synchronising message in the log comes after "sign-on or register". 
So, what is weird is that you seem to be able to enter your credentials 
in less than 0.708 seconds ... where it costs me at least 20 seconds to 
enter my credentials.
