Bug 689690

Description of problem:
Using <xi:include> to include a text file will sometimes fail with the same error that it would produce if the file was not found.  However the file is in the correct place and it seems that the content of the text file prevents it from being parsed.  The only file I have encountered this problem with is the LGPL 2.1 text file from the gnu.org site, http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt

Version-Release number of selected component (if applicable):
publican-jboss-2.4-1.fc13.noarch
publican-doc-2.5-1.fc13.noarch
publican-redhat-internal-1.5-0.el5.noarch
publican-2.5-1.fc13.noarch
publican-redhat-2.7-1.fc13.noarch


How reproducible:
Every time.

Steps to Reproduce:
1. Create a Publican book
2. Download http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt and add it to the extras directory
3. add the following line to the book in a suitable place:     
<programlisting><xi:include href="extras/lgpl-2.1.txt" parse="text" xmlns:xi="http://www.w3.org/2001/XInclude" /></programlisting>
4. Attempt to build the book
  
Actual results:
Beginning work on en-US
FATAL ERROR: XInclude:1604 in Chapter.xml on line 37: could not load extras/lgpl-2.1.txt, and no fallback was found
 at /usr/bin/publican line 672

Expected results:
Book builds with the contents of the file included as per a program listing

Additional info:
There is an odd character in this file that seems to prevent it from being parsed correctly.  It appears as a ^L when viewed within VI.  It occurs on lines all by itself, at a semi-regular rate within this file, around every every 50th lines on average.  Removing all instances of this character results in the book building as expected.

Extract from file:
