some bug adding new entry

Hello, 

I have this message while trying to add an InProceeding entry in
pybliographic. Nothing else happens, buttons "apply", and "add fields"
do nothing but printing the traceback.


Traceback (most recent call last):
  File "/usr/share/pybliographer/Pyblio/GnomeUI/Editor.py", line 635, in
menu_select
    new = self.update (self.database, copy.deepcopy (self.entry))
  File "/usr/share/pybliographer/Pyblio/GnomeUI/Editor.py", line 912, in
update
    if key != self.entry.key:
AttributeError: 'NoneType' object has no attribute 'key'



I guess I did something bad that put pyblio in a strange state, because
cancelling and trying again worked. I don't know how to reproduce it.

I'm using Pybliographic 1.2.9, packaged for ubuntu edgy.

sorry if it is a known bug, say if I can help some way.

br 

Sebastien
