Bad rabbitvcs-nautilus extension

Hello,
I figured out that the available rabbitvcs-nautilus extension is not the right one. It seems to be the extension for nautilus 2 as it installs itself in :
/usr/lib/nautilus/extensions-2.0/python/

The right place for python-nautilus extensions is :
/usr/share/nautilus-python/extensions

But the current extension is not the right one (bad import and with some modifications it gives a seg fault...)

As nautilus 3 extension version appeared in 0.15 version of rabbitvcs, it should be great to upgrade it or simply not keep rabbitvcs-nautilus in repo (just suggestion...) as it does not work at all...

Regards
