dependencies between {swfdec-mozilla, gnash-plugin} and nspluginwrapper

Yesterday I started to finish configuring some things that were left behind on my new laptop (amd64), and bumpped up with flash support for firefox. The thing is that swfdec didn't work, and gnash neither. Solution: remove nspluginwrapper. So I wanted to ask before opening a bug report: shouldn't there be a dependency on all 3 packages (don't know about others) so that you can only have one of the 3 packages (al least the plugins: nspluginwrapper, swfdec-mozilla, gnash-plugin) installed? -- Martín Marqués select 'martin.marques' || '@' || 'gmail.com' DBA, Programador, Administrador
