Bug#585994: Cannot open a local docbook document

Opening a local Docbook document whose file name ends with ".xml" and
that is not in a standard location seems to fail. I provide below a
minimal example docbook file to test with. I saved it as
/var/tmp/test.xml and tried to open it. This document seems valid. It
has been checked with the `xmllint --noout --xinclude --noent
- --postvalid test.xml` command.

On Ubuntu Lucid, it works with both `yelp file:///var/tmp/test.xml` and
`yelp file:///var/tmp/test.xml` commands. On Debian unstable (as of
2010-06-15), it fails with both commands. It used to work about a week
ago. Sometimes I see that yelp tries to open the document with Abiword,
but the latter fails to parse it.

Here is the example document:
