Comment 4 for bug 740815

First, thanks for the analysis. With Firefox' even more rapid release cycles I agree that it is worthwhile minimizing the xulrunner dependencies. I'll comment about/review the tasks individually.

Splitting the gnome-python-extras package is fine for natty. It will not effectively change any code (the alternative would be to port gwibber to GI, and build a gir from gtkspell, which is prohibitively intrusive at this point; needs to be done next cycle, though). Also, upstream development for this ceased, as it's obsolete (in favor of using GTK3 and PyGI), so we won't have to do much effort of keeping the two sources in sync.

FFE approved for this.
