Issue with satisfying od deps

[Werner Mahr]

Hi,

I got a problem with the way the build-deps are installed. When using 
pbuilder, everything works as expected, but when using qemubuilder I get 
prompted by a warning of phonon-backend-null, telling me that there will be 
no sound if I don't install any other backend.

This annoying in unattended automated environments. It happens not in 
Debian, but at least in the last 3 releases of Ubuntu. I doublechecked with 
pbuilder on i386 building i386, pbuilder on amd64 building amd64, 
qemubuilder on i386 building amd64, qemubuilder on amd64 building i386.

What can I try to get rid of this problem?
