What do you suppose is happening here?

This particular activity is crashing at about the same spot every time, and the log shows this same error every time. While I can usually decipher the Open Rails log, in this case it appears to be referencing an object viewer but does not specify the name of the object that's making it choke!

I seem to remember that when I've had logs like that the cause was a missing wagon or loco. I then used ConBuilder to trace it. Hope that helps.
