Johan Dahlin wrapped GtkMozEmbed in a python module, which is packaged as part of gnome-python-extras.

gtkhtml2 uses pango for i18n text rendering, etc. [gtkhtml2.codefactory.se] . The HTML rendering still needs work.

Note that Evolution uses libgtkhtml3, which is yet unwrapped.

Gustavo Carneiro did a XHTML-IM (XHTML-1.0 subset) renderer on top of gtk.TextView. It can be found at: [www.gnome.org]
