That's odd!

 I have been inserting conditional pass statements for years. just for 
the purpose of breakpoint, (before there were conditional breakpoints), 
and it has always worked!

That's Python 2.5 and 2.6 under Windows.

Actually, I have only used pass after if. I have never tried it after 
else or elif.
