>From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689054,

libgpod-cil package of the libgpod project has a wrong architecture entry:
- Normally -cil packages are arch-independent but,
- This one isn't because the library contains interoperability/marshalling
(unsafe) code.
- Package should be compiled differently, then, in each arch.
- Proof of this is the file configure.ac of upstream:
http://gtkpod.git.sourceforge.net/git/gitweb.cgi?p=gtkpod/libgpod;a=blob;f=configure.ac;h=669d433a47536ed5504eed12766f4876b476efa6;hb=HEAD
(Line 318, with different GMCS_FLAGS determined by ac_cv_alignof_double)
- The upstream bug is: https://bugzilla.gnome.org/show_bug.cgi?id=684876

Additionally, Banshee will need to be rebuilt to pick up the changes.

[Proposed Fix]
libgpod has already been fixed in Debian unstable, and will migrate to Debian
testing in 3 days. Hence all we need to do is sync libgpod 0.8.2-7 to Ubuntu
Raring, and backport this fix into quantal-proposed.

After that, Banshee will need to be rebuilt on Quantal and Raring.

[IMPACT]
Banshee users on 64-bit platforms (amd64) end up with packages that are built
for 32-bit platforms (i386), resulting in alignment issues resulting in
bgo#684876. It is unknown if any other issues are caused by this bug.

[TESTCASE]
1. Launch Banshee
2. Plug in iPod
3. Sync some playlists into the iPod.
4. Disconnect the iPod, and plug it back in.
5. Repeat steps 1-4, and see if the playlists are duplicated on the iPod.

[Regression Potential]
None for i386 users, and non-libgpod-cil users, as the changes only touch the
.NET bindings on non-i386 architectures. The binaries for i386 will remain
unchanged, as that's the arch libgpod-cil is built on for arch:all libgpod-cil.

The only known user of libgpod-cil is Banshee, which is already afflicted by
bgo#689054. Since the arch-specific changes only involve changing struct
alignment parameters, which were set incorrectly on 64-bit architectures in the
first place, the regression potential here is minimal as well.
