Steps to reproduce it:

1. Make sure lxml is installed

2. Open bpython (mine is changeset 238:fbe8addaf66f)

3. Type this:

   from lxml.etree import XMLParser
   help(XMLP

4. Now type the tab key for completing, bpython adds "arser("

5. Type tab again and bpython crashes with the following traceback:
