Created attachment 401358 [details] emerge --info output As of today, all portage output on my system includes the message: --- Invalid atom in /usr/portage/profiles/arch/amd64/package.use.stable.mask: >=media-video/mpv/mpv-0.7.3 See also first line in the output of my emerge --info ;) Looks like an extra "mpv/" was added when probably >=media-video/mpv-0.7.3 was meant.
Ooops, i should have read package.use.stable.mask more carefully, it looks like this was caused by the fix to bug 525148. I will post this report to the thread for bug 525148. Sorry for the noise.
