invalid message send to -[__NSPlaceholderArray initWithObjects:count:]: failed parsing encoding:

[DaveWest123]

what's going on doggie

the output tells me "it's likely a bug" so i am posting here. it could be the fox, too. maybe there's some incompatible character encoding shit that's 10.8+ and up. but i thought i'd share this anyways

10.7, running the fox in debug mode, i finally discovered why troubleshooting mode doesn't output the stats
