%%%-- System information --

Windows 7 64 bits
revision 60773 and 2.68 official release.

- Blender version with error, and version that worked ---

error in revision 60773 and 2.68 official release.
I don't think it ever worked.

- Short description of error ---

When an iterator is at its end (which means iterator.is_end == True) and is incremented again in an try/except clause, the RuntimeError this causes seems to be improperly handled. Referencing the object after the the except clause, that contains a return statement, so the remainder of the code shouldn't be executed, causes a crash.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

try to render an image in the attached blend file.
more generically, increment an iterator that is pointing to its final object in a try block, and refference it after the except clause, which contains a return statement.

%%%The problem seems to be more generic; it also crashes when using an if/else clause. I attachted another .py file that uses an if/else clause and causes a crash.
