Pixel aspect ratio bug

[Anonymous]

when adjusting the pixel ratio to 2.0 to match anamorphic shot footage I get the following issue:

# Error: AttributeError: file C:\solidangle\mtoadeploy\2017\scripts\mtoa\ui\globals\common.py line 2145: 'str' object has no attribute 'pixelAspect'

The mtoa plugin is correctly loaded in, everything works perfectly except for this little bugger.
I'm running build 3.0.0.1

We had this on a show and rolled back to previous build. I tested Arnold 3.1.0 today and it seems to have been fixed
