odd debug messages during NSPredicate.prediateWithFormat:argumentArray:

Happens with a stored array as well:

This isn't a MacRuby bug, the log happens in Cocoa. You probably need to initialize something before using NSPredicate.

Can this one get reopened? I don't see the error in Objective-C and Cocoa. Only in MacRuby thus far, I haven't tried Nu or F-Script yet with this example.

All of these work without the error though:

Sorry about that, it looks like a bug of MacRuby since the ObjC/GC version works. Re-opening.

[lsansonetti@…]

Workaround: add the following line before using NSPredicate:

NSPredicate.initialize

Should be fixed in r3937.
