Bug#664278: raise dependency on python-gtk2

[Holger Levsen]

package: pitivi

Hi,

thanks for maintaining pitivi! I just rebuild it (and gnolin) on squeeze and 
was disappointed when I started it just got a small box telling me pitivi 
needs gtk > 2.24.

So please raise the dependency on python-gtk2 to > 2.24.


cheers,
	Holger
