It seems like a bug in the fo branch of the DocBook XSL Stylesheets 1.77.x.
Let's give the following figure with the caption:
------
<mediaobject>
<imageobject>
<imagedata fileref="foo.png" format="png"/>
</imageobject>
<textobject>
<phrase>Foo</phrase>
</textobject>
</mediaobject>
<para>Blah blah blah</para>
-----
The caption in PDF output contains both open and close tags as
shown below:
-----
Blah blah blah
-----
I got the perdect results with no exttra tags in the next cases though:
-----
Blah blah blah
-----
XHTML 1.1 with 1.77.1
PDF with 1.76.1
PDF with 1.77.1 (moving the caption into the mediaobject).
