Script randomly exits for seemingly no reason with strange traceback

[Andrew Berg]

It's a rare occurrence, but sometimes my script will terminate and I get
this:

Traceback (most recent call last):
  File "C:\path\to\script\script.py", line 992, in <module>

That's it. And the line number is always the last line of the file
(which in my case is a blank line). I have not seen this on Linux (where
my script can run for days or weeks on a remote server), but only on
Windows where I do most of my testing (and it typically only runs for
minutes at a time). There may be bugs in my program, but I don't see how
Python should ever print a traceback like this.
