A bug!

Hi folks,

Im using Pybliographic 1.2.6.2 on Ubuntu 6.06 with LyX 1.3.7

Im using the vancouver.bst style from 
http://www.tug.org/tex-archive/biblio/bibtex/contrib/vancouver/

Im trying to create a Webpage entry, which isn't in pybliographics entry 
list by default (as far as I an tell).

For those purposes I've added some new fields : part [text], lastchecked 
[date] and updated [date])
I have then added a new Webpage entry and assigned a number of fields to 
it, including the three new ones (as optional)

So far so good ... If I enter a date into either the updated or 
lastchecked fields and try to save the bibliography (or try native 
editing), I get an error:

Traceback (most recent call last):
 File "/usr/share/pybliographer/Pyblio/GnomeUI/Editor.py", line 1125, in 
apply_changes
   new = self.editor.update (self.database, self.current)
 File "/usr/share/pybliographer/Pyblio/GnomeUI/Editor.py", line 889, in 
update
   result = item.update (self.entry)
 File "/usr/share/pybliographer/Pyblio/GnomeUI/Editor.py", line 382, in 
update
   del entry [self.field]
 File "/usr/share/pybliographer/Pyblio/Format/BibTeX.py", line 158, in 
__delitem__
   del self.dict [key]
KeyError: 'updated'

If I do not enter any data into those two fields (update, lastchanged) - 
there is no problem.

If I manually change the .bib file and add the two fields, there is no 
problem!

Thus: this is a pybliographer bug, it is consistently reproducible and I 
hope this is useful to the developers!
