uninstall gives errors ixspf_playlist_upload.install, expects parameter 1 to be array and Invalid argument supplied for foreach

Installed the module (dev) and disabled then uninstalled without adding to any content types.

The uninstall screen showed:

warning: array_filter() expects parameter 1 to be array, boolean given in sites\all\modules\xspf_playlist\xspf_playlist_upload\xspf_playlist_upload.install on line 13.
warning: Invalid argument supplied for foreach() in sites\all\modules\xspf_playlist\xspf_playlist_upload\xspf_playlist_upload.install on line 21.

I'm running PHP 5.3 and see these from time to time in modules that have not updated for supporting this version.
