### What steps will reproduce the problem?
Couldn't reproduce on original machine/repo since that one was updated and same error does not appear any longer.
So did from scratch on some arbitrary repo but caught another "problem" (or not -- for you to decide) that `annex` would crash if I did not init it yet:

```
the issue is different from original but still might be worth addressing one way or another (e.g. by providing a specific informative message that it was not yet init-ed)
