        * gdesktopappinfo.c:
	When adding an application as handling a mime type (but
	not as the default), copy the full list of desktop ids handling
	that type in before adding the new one on the end of the list.
	This means we're not accidentally changing the default by overriding
	the info from the later directories in the search path.
	
	Also, fixes small leak of removed_entries.
