This is a bug on Debian/Ubuntu side, let me explain.

1. Debian/Ubuntu ships libgpod in two main variants:
   a) libgpod4
   b) libgpod4-nogtk
   This is an artificial distinction that doesn't exist in upstream projects, but I would be fine if it was handled correctly. The only difference is that the -nogtk version is compiled with GDKPixBuf support disabled (thus doesn't support cover art) and therefore it doesn't depend on libgdk-pixbuf2.0-0.

2. However, Amarok's (optional) iPod cover support itself needs GDKPixBuf (as documented in README) *and* Debian/Ubuntu builds Amarok with GDKPixBuf enabled, Amarok's amarok_collection-ipodcollection.so links
libgdk_pixbuf-2.0.so.0 and thus the amarok package depends on libgdk-pixbuf2.0-0.

3. On the other hand, the amarok package depends on libgpod4 OR libgpod4-nogtk, which makes no sense, because it already pulls libgdk-pixbuf2.0-0. It should just depend on libgpod4 and you wouldn't ever run into this problem.

Debian/Ubuntu pacakgers, if you want to reduce Amarok dependencies, split
<prefix>/share/kde4/services/amarok_collection-ipodcollection.desktop
<prefix>/lib/kde4/amarok_collection-ipodcollection.so
into a subpackage. (but I'd be happied if you did not)

Jens, please report the above to Ubuntu/Debian (I had more luck with Debian last time) developers and CC me on the report. It should be fixed at least for their "testing" distro versions.
