Bug#839086: lintian: invalid-restriction-formula-in-build-profiles-field seems to be buggy

[Ximin Luo <infinity0@debian.org>]

Package: lintian
Version: 2.5.47
Severity: normal

Dear Maintainer,

For https://anonscm.debian.org/git/python-modules/packages/cysignals.git/tree/debian/control?id=68b7d79a24c7a8646d2d4e7a2f5b157f22c6876c

when I run `dpkg-buildpackage -S` then

$ lintian -i -I --pedantic --color auto ../cysignals_1.1.1+ds-1_source.changes
E: cysignals source: invalid-restriction-formula-in-build-profiles-field <pkg.cysignals.pari> python-cysignals-pari

but I am doing exactly as https://wiki.debian.org/BuildProfileSpec says

Additionally, if I change

Build-Profiles: <pkg.cysignals.pari>

to 

Build-Profiles: pkg.cysignals.pari

then dpkg-source will give me an error.
