--- Comment #12 from Alex Cherepanov <alex.cherepanov at artifex.com> 2011-10-05 03:59:40 UTC ---
My vote is for the checking of the object type because
- we already do similar checks elsewhere
- the explicit check avoids hard-to-understand bug reports
  about partly rendered pages.
- the stopped path is incomplete: no attempts are made to restore dictionary
  and operand stack to the original state if the failing procedure
  leaves some random junk.
- the stopped path doesn't provide a debug option to disable the error
  trapping.
