Device mapper failed to open temporary keystore device

[Murilo Opsfelder Araújo]

Hello, everyone.

Right after I enter my passphrase to unlock my cryptsetup partition,
it displays the following error and asks for cryptsetup password again
(it got stuck on this loop).

This issue was introduced in next-20150413.  next-20150410 is working just fine.

Any hint on how to debug this?

Unlocking the disk /dev/disk/by-uuid/<uuid> (sda5_crypt)
