Good suggestion!

I was able to locate the problem. I couldn't fix it ultimately, but the 
attached patch, which should be added to our snapshot, is a workaround 
(posted to wx patches as 854137). For unkown reasons, while selecting an 
invalid color is returned, and setting that invalid color will result in 
a wxASSERT. Unfortunately, this happens while rendering, ultimately 
freezing the desktop while debugging.
