 	* Fixed label definitions silently overwriting built-in script functions (bugreport:2806, follow up to r8027). [Ai4rei]
 	* Added temporary check to skill_delunitgroup to prevent crashes when 'group' is NULL and added some debug messages to track down the source of the crash (bugreport:3504). [Ai4rei]
