I pieced together a script that reads an XML job file. It renders a scene and moves on to the next entry. For some reason, every so often, Vegas crashes and gives the following message:

This occurs after a few renders. It always happens right at the end of a render, not in the middle of one. If anyone has any insight as to why this would happen, I would sure appreciate it.

I will post the code I am using here. The problem most likely lies in my bad coding. Thanks for the help.
