Hello,

this is my first post to this list, so good morning all!

I wrote to this mailing-list because the patch appeared the first time
on this list and AFAIK its aim is providing DAAP support to Rhythmbox.

I debianized for Debian unstable the 'gnome-vfs-daap' module [1],
following the Debian New Maintainers' Guide [2], and the package is
available for other people here:
	deb http://luca.pca.it/debian/ ./
	deb-src http://luca.pca.it/debian/ ./

I followed the instruction in the README and this is the output:
=====

As you can see, only 'gnomevfs-ls' works, but I guess this is correct.
OTOH, here the backtrace for 'gnomevfs-info', it it could be useful:

BTW, I'm here for any other tests you need.

Now I need the DAAP patch for Rhythmbox :-)
