When I open ardour it often segfaults while scanning plugins. When ardour opens it works properly for the only exception of the "scan plugins" function in preferences which often crashes ardour. Ardour works properly removing media-plugins/calf. Compiled ardour-6.3 from ardour.org works properly even with media-plugins/calf installed.

do you have dev-libs/sord-0.16.4-r1 installed? and what version of calf? can you try calf-9999?
(In reply to Miroslav Šulc from comment #1) > do you have dev-libs/sord-0.16.4-r1 installed? and what version of calf? can > you try calf-9999? I'm using media-plugins/calf-0.90.3 Yes, dev-libs/sord-0.16.4-r1 is installed I tried rebuilding dev-libs/sord-0.16.4-r1 and installed calf-9999 Same problem: ardour crashes on startup 4 times out of 5. When it starts it works without problems.
sord-9999 works fine for me
