Broken key mapping for Dvorak Simplified on mac

incorrect keys being detected when I attempt to set the controls. , is W . i E, etc.

When I originally purchased minecraft back in december i set it up with dvorak and had no issues. I have also been playing quite a bit under mavericks and have also had no issues, right up until last night.

Today my server was down so I thought id try out 1.6 and some of my key mappings weren't working, when I went into options to fix them the wrong values were appearing. I figured fine, still some kinks I'll file a bug.

Went back into 1.5.2 and the issue presented itself there too.
