Appearance properties settings work on Windows only

[lwrage]

I select a component in the AADL diagram and want to set appearance properties. The drop down menus work. There are three additional buttons (BTW, should the buttons have tooltips?), and when I click on either one of them I get the exception below. This works on Windows but not on Linux (tested with Ubuntu 16.04 and Kubuntu 17.10). Will test on Mac later today.

Exception happens on macOS also.

@joeseibel Can you test the fix on macOS?
