The Link in spice-gtk to the git repository [1] seems to be outdated. the real git repository of spice gtk can be found here [2] [1] http://gitorious.org/spice-gtk [2] http://cgit.freedesktop.org/spice/spice-gtk/
Its not a link to the git repo. Its a git to a website which tracks info about the development of the project. Containing links to the bug tracker and the upstream git repo as well as each of the developer's git repos where they push experimental code. Its hardly incorrect.
