WebHelp bug?

[Stefan Hinz <stefan.hinz@oracle.com>]

Building one of our books in WebHelp format gives a fatal error:

No template for "/book/chapter/mediaobject/imageobject/imagedata" (or
any of its leaves) exists in the context named "title" in the "en"
localization.
XPath error : Invalid type xmlXPathCompiledEval: 1
objects left on the stack.

A took some investigation to boil down the issue to this:

A construct like this makes WebHelp builds fail:

<mediaobject>
  <imageobject><imagedata .../>...</imageobject>
  <textobject><programlisting>...</programlisting></textobject>
</mediaobject>

The failure doesn't occur when the construct is changed to either of these:

a) Replacing <programlisting> with <phrase>:

<mediaobject>
  <imageobject><imagedata .../>...</imageobject>
  <textobject><phrase>...</phrase></textobject>
</mediaobject>

b) Removing the <imageobject>:

<mediaobject>
  <textobject><programlisting>...</programlisting></textobject>
</mediaobject>

Note that the construct that makes WebHelp fail is perfectly legal 
according to the DocBook DTD. We don't get any errors when building 
other formats (XHTML, FO, etc.). Since this is specific to WebHelp, I 
wonder if we've simply hit a bug.

Let me know, and I'll file a bug report on SF.net.
