Bug#759099: libcdio-dev: Causes every apt command to argue about unknown Multi-Arch type

[Axel Beckert <abe@debian.org>]

Source: libcdio
Version: 0.92-1
Severity: important

Dear Maintainer,

your recent upload to experimental causes the following APT warnings
with nearly every APT-based command, at least "apt-get update",
"apt-cache policy $packagename", and "aptitude":

$ apt-cache policy foobar
W: Unknown Multi-Arch type 'no' for package 'libcdio-dev'
W: Unknown Multi-Arch type 'no' for package 'libiso9660-dev'
W: Unknown Multi-Arch type 'no' for package 'libudf-dev'
W: You may want to run apt-get update to correct these problems
N: Unable to locate package foobar
$ 

While this seem to cause no actual harm, it's _very_ annoying to have
these warnings with every apt command. (Cc'ing the APT maintainers for
their information.)

I'm sure, I'm not the only one who would be _very_ happy if you could
fix this issue quickly. :-)

I will also file a lintian feature request as lintian does not show
_any_ warning about this in e.g. the libcdio-dev package yet.
