Doesn't ring a bell, but possible -- it's hard to remember 1.5.2 details.

Yes, many.

Yes, although there's no absolute guarantee it won't suffer new ones.  But
1.5.2 development ended a few years ago, and several people run Purify and
Insure++ against the current Python codebase.  I suggest moving to 2.1.2 if
stability is your most important concern.
