It looks like the temporary directory that the script wants to use,
shrink_test_case-tmp, already exists and contains a temporary file from
a previous attempt to use shrink_test_case.py.  This means that the
previous (failed) attempt has probably changed the copy of your
repository in a way that might not be correct.  So please remove the
shrink_test_case-tmp directory and start shrink_test_case.py again *with
a fresh copy of your repository*.

Technical note: shrink_test_case.py does the following:

while have_an_idea_for_a_change():
    temporarily_make_change_to_repository()
    if bug_still_present():
        make_change_permanent()
    else:
        undo_change()

So the previous run probably failed between
temporarily_make_change_to_repository() and deciding whether the change
should be made permanent or undone.
