ci servers that run on win32 don't have a assigned homedir in the env

it makes sense to avoid using it there or generally making the substitution lazily calculated

@RonnyPfannschmidt I am pretty sure that has been solved on one or other way in the meantime and can be closed. Correct?

no idea, please verify, its likely its not fixed

[obestwalter]

This was fixed by simply catching any exception that might occur fetching the homedir ...
