Sure, I've attached a backtrace done with 'bt full' on the older version that looks more comprehensible. I've built Kamoso from source on Buster, so maybe the dependencies need to be tightened. The new version fails to build from source for me, both on Buster and in an unstable pbuilder. Unfortunately it appears the buildd's are failing also: https://buildd.debian.org/status/fetch.php? pkg=kamoso&arch=amd64&ver=19.08.3-1&stamp=1576314481&raw=0
