Bug#672615: lintian: binaries-have-file-conflict misses virtual Conflicts/Provides

[Damyan Ivanov <dmn@debian.org>]

Package: lintian
Version: 2.5.6
Severity: normal

Hi,

Lintian shows several binaries-have-file-conflict warnings for 
firebird2.5 due to it not considering the virtual packages provided 
and conflicted with.

Example:

W: firebird2.5 source: binaries-have-file-conflict firebird2.5-classic-common firebird2.5-super usr/bin/fbstat

But:

Package: firebird2.5-classic-common
Provides: firebird-udf, firebird-utils
Conflicts: firebird-udf, firebird-utils, …

Package: firebird2.5-super
Provides: firebird-server, firebird-utils, firebird-udf
Conflicts: firebird-server, firebird-utils, firebird-udf, …

So in reality the two packages do conflict with each other and there 
is no real file conflict.


Sorry for not providing a patch, I have delayed filing this bug enough 
already hoping to be able to find time for a patch.


Thanks,
    dam
