No. If you tried catching AttributeError and it didn't work then I'd
guess that the AttributeError is a secondary result of the initial
error.
This part of the traceback,

> raise error, "need 'c' or 'n' flag to open new db"
> error: need 'c' or 'n' flag to open new db
indicates that some sort of custom error, probably defined in the
anydbm.py module.
Catching the execption and binding it to a var,
>>> try:
... db = shelve.open("meh", "r")
... except Exception, err:
... E = err
...
Exception exceptions.AttributeError: "DbfilenameShelf instance has no
attribute 'writeback'" in ignored
>>> E
<anydbm.error instance at 0xb7d8270c>
So:
>>> from anydbm import error
>>> try:
... db = shelve.open("meh", "r")
... except error:
... print 'Aha! got it!'
...
Aha! got it!
Exception exceptions.AttributeError: "DbfilenameShelf instance has no
attribute 'writeback'" in ignored
Well, that catches the error, but I don't know what's going on with the
additional AttributeError or what to do about it.
