Thanks for the complete printout. :)
Actually, the error is happening in a vray script. So it looks like your vray install is somehow corrupted. Since you have posted it here and not in the chaosgroup forums, I assume you installed both plugins at the same time and it looked more likely that Corona caused it. Have you been using Vray before or have you indeed installed both at the time time or in some other particular order?
I'm pretty sure Corona is not breaking anything since I cannot see how the Corona startup script (which I wrote) could interfere with Vrays.
If you want to test it further, try to uninstall and install Vray - test if it works, and try again adding a Corona installation at some point (it would require several test cases in different orders to be sure).
Btw, you can upload screenshots here in the forum using the attachment function when writing a reply, no need for any image hosting service.
