empty FILE_SIZE on repository

[Alexander Nasonov <alnsn%yandex.ru@localhost>]

I use pkgin to install packages I build myself with pkg_chk inside
chroot. I run

pkg_info -X -a | gzip -c > pkg_summary.gz

to generate pkg_summary.gz.

I started getting these warnings recently

warning: package openssl-1.0.2n has an empty FILE_SIZE on repository.

and "download mismatch" failures.

Any ideas what is going on here?

Thanks,
Alex
