I know this is a very weird scenario and probably something that
shouldn't be done. Nevertheless I thought I'd report this. Please find
the backtrace attached.

Steps to reproduce:

mkdir -p foo/bar
touch foo/bar/file
got init foobar.git
got import -r foobar.git -m 'test' foo
got checkout foobar.git
cd foobar
echo 'blah' > bar/file
got stage bar/file
mv bar/file bar/new_file
got unstage bar

$ got -V
got 0.104-current
