Summary: bsddb.first()/next() raise undocumented exception

Initial Comment:
bsddb object's first() & next() methods raise an undocumented 
exception.  Wouldn't returning None make much more sense?  
And shouldn't this be documented? 

Python 2.3a2+ (#2, Mar 21 2003, 22:13:05) 
[GCC 3.2.3 20030316 (Debian prerelease)] on linux2
>>> import bsddb
>>> h.bsddb.hashopen("testdb")
>>> h.first()
------------------------------------------------------------
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.3/bsddb/__init__.py", line 134, in first
    rv = self.dbc.first()
DBNotFoundError: (-30991, 'DB_NOTFOUND: No matching key/
data pair found')

Note: The same exception appeared for the equivalent dbhash 
methods.  But I assume this should be fixed if this bug is fixed.
