Comment:
Rigth, it is a feature request not a bug. I came across it when looking at
hwdb-client which depends on canvas.
The way it is now it also installs all the gnome libraries which it does not
use.
Canvas will have to be moved out anyway when it is replaces by a gtk only
equivalent :)
But I agree it is not a priority.
