Failed to extract LUKS key ... (errno=95)

kjotte@daedalus:~$ cryptmount lukstest
Enter password for target "lukstest":
Failed to extract LUKS key for "lukstest" (errno=95)
Failed to extract cipher key

This issue has been fixed upstream:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888444

Please consider backporting this fix into LTS.

As ecryptfs is no longer supported, I wish to use a LUKS image file in my home directory so it is backed up as part of my normal workflow. A functioning cryptmount would facilitate this more easily than custom shell scripts.
