I have also seen this, especially in non-console frozen programs.
It isn't really obvious, because tracebacks aren't visible.

py2exe 0.5, for non-console exes, automatically redirects sys.stderr
into a logfile, the name derived from the exe-name, and sys.stdout into
a file-like objects which will simply ignore the string.

Of course, this has nothing to do anymore with the OP's problem.
