Sorry about the delay on this.
I got kind of distracted this week.

Looking close now.

If this fails then the error is never cleared or handled.

I think checking == NULL and then calling gdbpy_print_stack is appropriate.

This looked a little weird, but I verified from the docs that it is ok.

I think this still needs a NEWS entry.
