Created attachment 340078 [details] Capture of the bad display of the keywords of app-emulation/qemu See the attachement
This fact is in fact quite general and disturbing. After looking at some ebuilds, it seems to me that the disappearence is linked to the switch from EAPI="4" to the EAPI=5 (note the absence of quotes), which here happens from the 1.1.2-r2 ebuild to the 1.2.2-r2 ebuild. Just my two cents.
I can comfirn that, packages.gentoo.org looks really bad as many pkgs now are EAPI=5 and the pkg info is just blank for those ebuilds.
