You're right; it does. `unset' is a builtin, so all of the shell's word expansions are performed before it is run, including globbing. If you don't protect the argument by quoting it, the nullglob extension will remove it when there are no matching filenames. Running the script with `bash -x' will show what's happening. There's no `fix' -- everything is working as it's supposed to. You've just combined things in a way that produces unexpected results.
