Found that after enabling Google Docs portfolio exporting text from modules using the Portfolio API to Google Docs fails.

Reproduction instructions :

• Enable 'portfolios' and Google Docs portfolio plugin at site level.
• Create a post in any forum.
• Select Export link and select Google Docs (if choice presented)
• Instead of getting success message you get:

Failed to send your data to the selected system: original error was portfolio_gdocs/sendfailed

With debugging turned on:
