Thanks for looking into this.

Yes, I suspect that too.
I'm using apt sources at http://www.deb-multimedia.org.
I believe both bugs I filed on apt-file have the same source.  See
bellow.

Using the later hint, I found out the possible cause of the problem.
The files /var/lib/apt/lists/*_InRelease the header:

	Origin: Debian
	        ^^^^^^
to just _one_ word.  deb-multimedia uses 3 words:

	Origin: Unofficial Multimedia Packages
	        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

and the parser does not make the distinction.  One may argue
deb-multimedia is at fault here, and I would agree.  Still if the
indextargets format specifier would use another field separator (say
'|' instead of ' ') parsing would work much better.  Say:

'$(IDENTIFIER)|$(ARCHITECTURE)|$(ORIGIN)|$(CODENAME),$(SUITE)|$(FILENAME)'

What do you think?
