I bet you are -- it's Python, not C++. 
* You understand the problem: both how the current version
works and how it should work.
* You know how to test for the problem.
That's the hard part.
The rest is just typing. And dealing with bugtracking systems
(personally, I find that to be the most difficult part).
Actually, just entering the bug along with a small demo app
showing the problem is probably all you really need to do. I'm
sure the library maintainers would appreciate a patch as well,
but if they're anything like me, me they apprecate a demo app
and test cases a lot more.

My apologies: I forgot to tell you how to _get_ atime and
mtime, but I see somebody else already has. There is one
tricky bit (as explained on a qmail man page). If the file was
last read less that a second before the message was added, you
could end up with the case where atime==mtail (they only have
1-second granularity). Apparently there are MUAs that think
that means "no new mail", so qmail's delivery code checks for
that case and sets atime = mtime-1.
 Admit it, you thought I couldn't work a shot at C++ into
