Bug#688320: lintian: --suppress-tags not working?

[Thorsten Glaser <tg@mirbsd.de>]

Package: lintian
Version: 2.5.10.1
Severity: minor

Hi,

in a Debian wheezy cowbuilder instance on one of our Jenkins
buildbots, I am calling lintian like this:

lintian -vIi --display-experimental --pedantic --suppress-tags package-has-long-file-name -X nmu --allow-root /tmp/buildd/fusionforge_5.1.1+evolvis70~snapshot.20120921.145452_amd64.changes

And yet, still I get:

[…]
N: Processing binary package fusionforge-plugin-projectlabels (version 1:5.1.1+evolvis70~snapshot.20120921.145452, arch all) ...
W: fusionforge-plugin-projectlabels: package-has-long-file-name 83 > 80
N:
N:    The package has a very long filename. This may complicate shipping the
N:    package on some media that put restrictions on the length of the
N:    filenames (such as CDs).
N:
N:    For architecture dependent packages, the tag is emitted based on the
N:    length of the longest architecture name rather than the name of the
N:    current architecture.
N:
N:    This length will be written in brackets after the actual length.
N:
N:    Refer to http://lists.debian.org/debian-devel/2011/03/msg00943.html for
N:    details.
N:
N:    Severity: normal, Certainty: certain
N:
N:    Check: filename-length, Type: source, binary, udeb
[…]

Am I doing something wrong or is tag exclusion really
not working right? I’d like to not display this tag for
snapshot builds because of the automatically appended-to
version (also the reason for -X nmu, as it changes the
debian/changelog file machinally for them).

Thanks in advance,
