I tried to reproduce this on fresh VM (NetBSD 9.99.8 amd64) but it
works there. There were a couple of bugs (specifically when
redirecting the output to less) which I fixed a while back (in
revision 1.42 of apropos-utils.c). I think this should not be
happening anymore, could you confirm if it is still an issue and any
specific setup or steps to reproduce?
