Fixed this with three changes: * filter_glob is now 255 char max (63 could be a bit limited in some rare cases). * IO templates now explicitely define max len of that property (such that scripters are aware of the limit). * ED_fileselect_set_params() is now safe regarding too long strings from a 'filter_glob' op property.
