Agreed, however we can't avoid crashing here, as this happens in the
C/Objective-C side of the bridge. MacRuby will let you pass most objects to
native APIs, but without proper BridgeSupport signatures, these objects might
not be properly converted.
In this case, NSArray tries to call something that isn't a pointer to a block
function. And the Objective-C runtime doesn't annotate properly block
arguments, so BridgeSupport signatures are needed by MacRuby.
