+### Please describe the problem.
+
+follow up on this particular issue from [https://git-annex.branchable.com/bugs/merge-annex-branches__61__false_-_automate_and_extend/#comment-5d414fbc11cff204b9bcc93685e3bbcb](https://git-annex.branchable.com/bugs/merge-annex-branches__61__false_-_automate_and_extend/#comment-5d414fbc11cff204b9bcc93685e3bbcb) . 
+
+### 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)
