Comment 3 Pavel Nakonechnyi 2015-10-12 17:24:53 MSK 
Приложил патч, который скорее всего решает проблему, так как тут: https://bugs.archlinux.org/task/38560 аналогичная проблема решилась.

Пересобрал в hasher из репозитория git://git.altlinux.org/people/zerg/packages/dirmngr.git с указанным патчем, работает.
