Bug#581785: Icons still not visible in kde notifications

[denk@post.com]

Hello,

as I've sent you already on June 15th the problem with missing icons in 
kde notifications is not fixed (e.g. the attached picture of that mail 
from June 15th). The last uploaded hplip-packages don't fix that, too! 
Could you please look into it again? For your information: the icons in 
kde notifcations of network-manager-gnome are shown correctly, perhaps 
you can use this package as an example how to fix that problem!?

Thanks.
