Summary: regression error: epub file no longer validates

Initial Comment:
Hi, there, I noticed a bug that popped up which was not present at 1.75 or 1.7.6. The index.epub file is produced, but it contains an extra (and empty) entry on the content.opf file.

Message:
I am affected by this bug as well in the DocBook 5 project of this
repository:

https://bitbucket.org/shlomif/the-enemy

Type make to create the EPUB (you may need to install some paths). After I
validate the resultant EPUB using this online validator:

http://threepress.org/document/epub-validate

It reports the following errors:

Message:
A few notes. I used as simple a docbook project as possible, so chances are
that this bug affects all docbook to epub projects.
