FS#50278 - [gsfonts] Firefox uses regular font instead of bold

Since upgrading the gsfonts package from 20150811-1 to 20160531-3 (reverting fixes the issue), Firefox stopped using a bold font (using a regular weight font instead) in some cases where 'font-weight: bold' is specified, for example on GitHub for user names.

Steps to reproduce (… at least on my system):

* Install gsfonts (possibly as a dependency of evince) and Firefox
* In Firefox, navigate to
* At the end of the first message, "@rust-lang/compiler" should be in a bolder font than the rest of the message. On my system with up-to-date packages, it has the same (regular weight) font as the rest of the message. The Fonts panel of developer tools shows that "NimbusSans-Regular" is used, even though /usr/share/fonts/OTF/NimbusSans-Bold.otf exists next to /usr/share/fonts/OTF/NimbusSans-Regular.otf.

Steps to confirm responsible package:

* Downgrade with "sudo pacman --needed -U /var/cache/pacman/pkg/gsfonts-20150811-1-any.pkg.tar.xz" (assuming this old version is in the cache)
* Restart Firefox
* Navigate to again
* "@rust-lang/compiler" is now correctly in a bold font. The devtools show that "NimbusSanL-Bol" is used.

There was indeed an error spewd by the install scriptlet about some OTF font not properly declaring its weight. That's why I added "&>/dev/null" but now I cannot reproduce it. Could you please report this upstream? I'd really prefer not to edit the files in our PKGBUILD. Cheers.

No response so far.

Gaetan, do you have more details on what the issue is?

Simon: First off, I cannot reproduce your issue. If I open the github issue page you've mentioned in Firefox, the font used for "@rust-lang/compiler" is "Roboto Medium" which is a remote font Firefox gets from "". So my first question to you is: why don't you get that font too? That's what github's CSS specifies.
