Building a dynamic class factory ( +load init order)

Hi,

I have some old code from the Tiger aera that fails on Leopard. Basically some classes call

+ (void) load
{
	NSDictionary *aDictionary = [aDictionary dictionaryWithObjectsAndKeys:
		[self class], @"class",
		@"plugin name", @"name",
		 nil]];
	[TELibraryFactory registerClass:aDictionary];
}

with a implementation like

+ (void) registerClass:(NSDictionary *) aClass
{
	if( !sRegisteredClasses )
		sRegisteredClasses = [[NSMutableArray alloc] init];
	[sRegisteredClasses addObject:aClass];
}

Seems I relied too much that the Foundation classes are already loaded and initialized when +load is called - now the dictionary creation already crashes.
Is there any better way to prevent I have to add


	[[TELibraryFactory register:[TESubclass1 description]];
	[[TELibraryFactory register:[TESubclass2 description]]; 	
	// ...
	[[TELibraryFactory register:[TESubclassN description]];

manually in a separate file and keep that in sync each time a new class is added?
