We (the GNOME Team) are planning on dropping a few packages from Factory. It's mainly packages that are no longer maintained and start to cause trouble with newer GNOME versions anyway.
the 'main' offender is libbonobo (no, fixing it is not an option, it's just a bandaid)
Together with this, we will drop this tree:
libbonobo : bareftp (unmaintained, declared dead by upstream) gnome-commander (if there is ever a new release with modern tech, it might come back) gnome-desktop-sharp2 gnome-do (probably not the biggest loss nowadays - but still sad to see it go) gnome-do-plugins gnome-sharp2 ignuit libbonoboui libgnome libgnomeui mono-upnp perl-Gnome2 taglib-sharp tuxpaint (Bjorn submitted a version to the devel branch that should work without these legacy deps - up to the maintainer to decide if they want to keep it or not)
