function _allow_all_file_extensions_fix_validator in Allow All File Extensions 7

This ugly little hack of a function recursively crawls through the form and adds an empty file_validate_extensions array to every managed_file element that doesn't already contain one. I shouldn't have had to do it this way, but unfortunately Drupal 7's smarter-than-you file extension validation code is added while the form is being generated, so there's really no other way.
