'debiandoc2dbk -1' fails

[Bob Bernstein <poobah@ruptured-duck.com>]

I have a simple debdoc file "simple-epa-howto.sgml" that 
responds correctly (viz produces the desired output) to 
debdoc2html and debdoc2pdf.

The .sgml file also seems to produce ok output with 
debiandoc2dbk; at least, the appropriate .dbk files are created 
in the expected subdirectory. (I haven't yet taken things 
farther than that.)

However, here's the problem:

$ debiandoc2dbk -1 simple-epa-howto.sgml
Cannot create file ./simple-epa-howto.dbk.
 at /usr/share/perl5/DebianDoc_SGML/Format/XML.pm line 149.

Thoughts, anyone?

Best regards,
Bob Bernstein
