Well, typically, unless otherwise safeguarded, all VTK object access 
must be done from the main GUI thread of a Windows app.

Are you making VTK method calls from a multiple threads?

At least you have a way to keep it from crashing. As to whether it's a 
feature or a bug, I'll let others chime in...
