The last patch broke make_bugzilla_version_list() which is used by account.php and admin/editAppVersion.php. That means that new users can not create accounts and maintainers cannot edit their versions.

The same code on my machine works fine with my test databases.
I do not know how to fix this other than reversing the patch.
