Description of problem:

Pybliographic, the GTK frontend for pybliographer, crashes when a medline query is launched, after importing an existing bibtex database.  


Version-Release number of selected component (if applicable):
Name       : pybliographer
Version    : 1.2.12
Release    : 3.fc11

How reproducible:

Exceedingly so.  It appears to be after importing any bibtex database.


Steps to Reproduce:
1. Open pybliographic
2. Open the medline query window (File -> Medline Query)
3. Search for a random topic (e.g 'Cheese')
4. Copy a reference from the list given in the new window to the first window
5. Save the database in the first window
6. Exit pybliographic
7. Open pybliographic
8. Import the database saved in step 5.
9. Open the medline query window (File -> Medline Query)
  
Actual results:

Program crashes.


Expected results:

Program lets you query medline and add more references to the database.


Additional info:

Running pybligraphic in a console to perform steps 7-9 results in the following being output in the console:
