During sunday I worked to package it, and by the time the release was announced, packages were (mostly) ready in our svn. It runs fine (no real changes since 4.4rc2 so there's no urgency).
4.4 won't be uploaded to unstable soon, because of the freeze status. It may be uploaded to experimental in the future.
I've made/uploaded preliminary packages to my repository. There are there packages for ppc and i386. ppc packages are built against gtk 2.10 from experimental, and they run fine (except mousepad with line numbers activated, known bug in gtk 2.10.7). i386 packages are built against gtk 2.8 except gtk2-engines-xfce, built against gtk2.10 because it now uses in the packaging a call to a module only present in gtk 2.10.
If you want to install Xfce 4.4 on i386 via my repository and don't wan't to switch to experimental gtk 2.10, you can do as follow:
apt-get source gtk2-engines-xfce
dpkg-source -x gtk2-engines-xfce_2.4.0-1.dsc
cd gtk2-engines-xfce-2.4.0
vi debian/rules
dpkg-source -x gtk2-engines-xfce_2.4.0-1.dsc
cd gtk2-engines-xfce-2.4.0
vi debian/rules
Now you just have to remove the call to dh_gtkmodules.
Then:
vi debian/control
In the Build-Depends: line, change the dependency from gtk 2.10 to gtk 2.8. (libgtk2.0-dev (>= 2.8) should be ok).
Then just rebuild the package as usual:
apt-get build-dep gtk2-engine-xfce
dpkg-buildpackage -rfakeroot -us -uc
dpkg-buildpackage -rfakeroot -us -uc
As alway, don't use those packages if you want stability. Current i386 packages are not up to date (as I can't rebuild quickly for this arch), and they can change at anytime. If you still want to test, don't report bug on Debian BTS but rather on IRC (#debian-xfce@freenode).
Happy testing!
