python-gnome2 should be a package dependency

[BrokenKingpin]

After installing DockBarX on Xubuntu 11.04 beta (Xfce 4.8) and adding it to the panel using XfApplet DockBarX would crash with the following error:

raceback (most recent call last):
File "/usr/bin/dockbarx_factory", line 30, in <module>
import gnomeapplet
ImportError: No module named bonobo.ui

This was resolved by installing the python-gnome2 package from the Ubuntu repos. This package should be a dependency when installing DockBarX. This probably is not an issue under Gnome as that package would already be installed, but not under Xfce.
