Thanks for the pointer.

The curious thing in this case is that GIT_DIR is not saying anything at
all, other than the default. Emacs should not error under such
circumstances. In my specific case, even a silent failure would be
acceptable (cause I am using Emacs in batch -- I can't even see the mode
line!).

There's a patch attached that Bug report which never seems to have been
applied.
