Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

For files that are placed in a subdirectory (where there's no .git) of a
git repo, vc now thinks a file unchanged even if there are changes.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG.

It returns the empty string "" as well.

I think it might be due to incompatibility between git 1.4.x and 1.5.x
as all new repos do not have this problem. This bug can be closed. Thank
you very much for your help along the way.

Best,
