Renaming file fails in gitfs

[balazser]

Anybody experienced that renaming file like mv a b fails with the error message:

mv: cannot move 'a.sh' to 'b.sh': No such file or directory

then git status shows the file is removed but not added:

On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    a.sh
