Just upgraded Confluence from 4.0.3 to 4.0.5, and now the 'Confluence Changes in the last 24 hours' notification email is sent out as completely blank, just an empty email body. The behavior is the same if I manually run the 'Email Daily Reports' Scheduled Job.

The site itself behaves as expected, including the Dashboard 'recently changed' widget and sending a Test Email from the Admin panel arrives as expected, with body content.

This seems to have cropped up before:
