Comment 3 for bug 257713

In http://bugzilla.gnome.org/show_bug.cgi?id=450209 there's a comment that says:

> librsvg includes svgz support, but it is optional and has to be enabled at
> compile time. (See the configure.in file at
> http://svn.gnome.org/viewcvs/librsvg/trunk/configure.in?view=markup for the
> --with-svgz flag).

> So... compile it that way, or file a bug with your distro.

So, is it really an upstream bug? I have still this bug on Ubuntu 8.10.
