Public bug reported:

I am debugging a Python unit test using pdb. In my code I use the
following:

import pdb
...

    pdb.set_trace()

This drops me into a Pdb prompt (handled by readline).

When entering 'n' a few time to step I encounter a segmentation fault.
Details and backtrace are in attached log file.

I tried using apport to report this, but apport keeps crashing while
analysing the issue :-(
