k3b should depend on udisks, otherwise: "No optical drive found."

[Robert Euhus]

I am using Xubuntu 12.10 and I installed k3b, but when run it only says "No optical drive found. K3b did not find any optical device in your system." So it's pretty useless as a CD/DVD-burning application.
In the terminal I get :
QStringList Solid::Backends::UDisks::UDisksManager::allDevicesInternal() error: "org.freedesktop.DBus.Error.ServiceUnknown"
Which led me to install the package "udisks" and everything is fine.

Further investigation shows: k3b depends on libsolid4 which in turn only recommends udisks. Since libsolid4 was already installed previously without recommends udisks was not installed.

Solution: installing udisks fixed the problem.

Additional info:
1) lsb_release -rd
Description: Ubuntu 12.10
Release: 12.10
2) apt-cache policy k3b libsolid4
k3b:

3) What you expected to happen: have k3b find the optical drives so that I can burn a CD.
4) What happened instead: k3b did not find any optical drives. Instead it showed a "System Configuration Problem": "No optical drive found. K3b did not find any optical device in your system."

Thank you Robert for your bug report, and for the solution !
I was also affected in Ubuntu 13.04 and still am in 13.10.

Best regards.
