Bug#680602: libav-dbg: bogusly Depends: libavcodec53 (= ${binary:Version})

[Stepan Golosunov]

Package: libav-dbg
Version: 6:0.8.3-4
Severity: important

libav-dbg is not installable together with libavcodec-extra-53 due to
bogus dependency on libavcodec53 (introduced in 6:0.8.3-2):

# apt-get install libav-dbg libavcodec-extra-53
Reading package lists... Done

libavcodec-extra-53 is already the newest version.
libavcodec-extra-53 set to manually installed.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libav-dbg : Depends: libavcodec53 (= 6:0.8.3-4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


As libav-dbg does not provide debug data for libavcodec53, it should at
most depend on
 libav-regular-dbg (= ${binary:Version}) | libav-extra-dbg (= ${binary:Version})
instead of
 libavcodec53 (= ${binary:Version})

By the way, is there any need for separate libav-regular-dbg and
libav-extra-dbg to exist at all? Given that the packages use build IDs
now, all their contents could be placed into libav-dbg.
