[Zope] TextIndexNG and mime type

[Kevin Carlson]

I just installed TextIndexNG and I cannot seem to get it to create an index
on existing catalog context.  I keep getting the error(s):

"text/x-unknown-content-type" not registered in registry "converters"
or,
"application/octet-stream" not registered in registry "converters"

or something similar.

The first error message occurs if the content_type is
application/octet-stream.  The second error occurs only on selected items
that have content_type of application/pdf.   Can anyone offer an idea as to
what is going on?

Thanks,

Kevin
