New version is out since March 29th, no kitten killed ;) Just copying the 1.4.00.4855 ebuild (w/o the patch) works fine, apparently. Thanks a lot.
I'm getting segfault after update to this version: Media[8427]: segfault at 90 ip 0000555eb41630e2 sp 00007f6a5d7f8f70 error 6 in teams[555eb38e9000+53d2000] net-im/teams-1.4.00.7556 (-system-ffmpeg -system-mesa KERNEL="linux")
Closed as this version is on gentoo repository
