On the bleeding edge I get:

$ ./miniruby  -e "module H; end; class Hash; include H; end; p NSDictionary.dictionaryWithDictionary('foo' => true)"
NSInvalidArgumentException: *** -[NSCFDictionary initWithObjects:forKeys:count:]: attempt to insert nil key at keys[0] (RuntimeError)

Should be fixed in r3954.
