git version 1.6.6.78.gbd757c
HEAD points to a non-existent branch refs/heads/master. Normal checkout
origin fails with:
error: Entry '.cvsignore' would be overwritten by merge. Cannot merge.
(the working tree does indeed contain this file). So I tried checkout -m
and git crashed. Workaround for me was reset --hard origin; checkout
origin. I have the repository backed up in case someone wants to try
themselves.
