Simple UI with combo boxes

Description of Problem:

Have a very simple winforms application with a few labels, comboboxes, and groups.  The layout is manual so there should be no odd layout issue.

Everything renders except the comboboxes.  Furthermore repeatedly emits the error:

   mono[10709] <Error>: CGBitmapContextCreateImage: invalid context 0x0

Have tried the standard 2.10.9 and 3.0.1 packages on OSX Lion.  

Steps to reproduce the problem:
1. Run the enclosed application on Linux (should render 3 comboboxes)
2. Run the enclosed application on osx (does not render comboboxes)

How often does this happen? 


Additional Information:

See enclosed dummy application (there is no application behavior, just a layout).
