Bug description:
I'm running OpenERP version 5.0.1 on Ubuntu 8.10.

I select a procurement order in the desktop client and from the Plugins menu, I choose Execute a plugin. I double click Print Workflow (Complex). I quickly get a blank page. When I check the server output, I see this:

[2009-07-28 11:59:01,045] ERROR:workflow:[01]: Exception in call: Traceback (most recent call last):

I've tried several procurement orders in different states, and they all cause the same error. I've tried the basic Print Workflow, and it works. I've tried the complex workflow on a production order, and it works.
