Picklist options no longer generating anything


We are finishing up a 4.0 system and were trying to run close out documentation of the picklists and form data.
The forms seem to generate, but the picklists are now all blank on each tab. AS recently as December, they were generating without error.
There are no messages. The routine runs so quickly that it looks like it is just generating the tabs without any other activity.
We have tried it on 2 different platlforms with the same results, including doing all, subset, and just a single entity in the customizations.xml file.
Office 2010 on Windows XP
Office 2010 on Windows Vista
No substantive change on either platform. Example customization file with just one entity is attached.
