After poking around a bit, it turns out that upgrading libcap-ng0 from
0.7.7-3.1+b1 to 0.7.9-1 triggers this problem.

A workaround in case of searx (and maybe others) is to comment the line

autoload = true

in /usr/share/uwsgi/conf/default.ini. If that line is commented, then it will
work again even after upgrading libcap-ng0.

Thanks!

cheers, josch
