unexpected EOF on publishing mongodb snapshot

[smarmie]

When publishing the snapshot of the mongodb mirror, aptly panics with unexpected EOF on package /mirror/aptly/pool/b9/13/mongodb-10gen-unstable_2.5.1_amd64.deb

This looks like #440, but I don't know if it's the same cause.

Using aptly 1.0.0 (but also saw this on 0.9.7) on debian 8.7

Looks like really broken archive though:
