I have had this problem, too.  After rendering the same scene about half a 
dozen times, PVEngine will crash.  Restart it, and you get another half-dozen
tries before it crashes again.  If a stack traceback, register dump, or other
debugging information would be helpful, I can make it crash again and get the
required information.

Speaking of making POV crash, I can make 3.1b4 crash repeatably when I stop a
render and attempt to clear the message window by right-clicking on the small
part of the message window visible below the editor pane.  The error is:

  Application Error

  Exception EInvalidOperation in module EDITDLL.DLL at 0001403A.
  Control 'Editor1' has no parent window.

If I then press the OK button, it terminates PVEngine.  When I restart 
PVEngine, I get an access violation (NT STATUS_ACCESS_VIOLATION, Win95
probably calls it an Exception 0D) at PVENGINE!AUTO+2D6E4.  If I ignore 
the error, it fixes itself and goes on.

Since the editor in the beta version isn't the same as the one in the final
version, it probably isn't a problem, but someone should take a look at it
just in case.  For what it's worth, the problem did not exist in 3.02.
