Well, actually pdb has the same bug. If you call post_mortem before
there's been an exception, you'll get one - from
post_mortem. Hmmm... perhaps just post_mortem trying to be helpful? 

It may be that ipython wants to test for this before calling
post_mortem. But with respect to pydb, the right thing is to (also)
make a check in post_mortem -- one shouldn't assume the only time
post_mortem will ever get called is from ipython.

Should other pdb users feel this a pdb bug too, some good citizen
might submit a Python bug report. (I probably won't.)
