Cannot expand templates with tab key

[infodroid]

Binary package hint: scribes

On upgrading to Ubuntu 9.04, Scribes no longer expands templates using the tab key. In fact, the name of the template is just deleted in the editor.

Reproduce:
1. Create a template
2. In the editor, type the template name
3. It will now turn bold and Scribes will say in the status bar that it detected a template
4. Press tab
5. The name of the template is erased from the editor

I have attached a Python traceback of the error.
