Some bugs to post here. This is from a clean installation and WTF cleanup. I'll try to look for some more bugs but this is what I've seen so far.
-reducing the text size on Player Frame -> Healthbar crashes below 0.01 text size. I believe it occurs on all other frames. Below 0.01, was there supposed to be an off setting like your others? Tested Player/Target Frames.
-error when configuring settings of Player Frame -> Portrait. It could have something to do with being able to change text values of a portrait bar that doesn't really have any text. | Options.lua:447 attempt to index field '?' (a nil value)
-got this error after relogging. I'm sorry, I can't really tell you how I got it but here's a url of the error message.
