Version 16.03.90

I use encrypted BR-Ds and dolphin detects them and mounts / decrypts them. Fine. But if one after that tries to unmount them the cryptsetup binding stays in place and they cannot be ejected unless one does a manual cryptsetup close on the automounted device.

It should not only unmount the device but also detach the cryptsetup device mapping!

Reproducible: Always

Steps to Reproduce:
1. Put in BR-D with Luks dm-crypted iso
2. open it with dolphin which asks for password and mounts it
3. Try to unmount / release / eject it via dolphin

Actual Results:  
the cryptsetup binding stays in place and they cannot be ejected unless one does a manual cryptsetup close on the automounted device.

Expected Results:  
It should not only unmount the device but also detach the cryptsetup device mapping!

It is nice that dolphin supports encrypted devices, but so far the support is "half-assed". People without a deep knowledge of the underlying encryption process will not be able to manually detach the device to eject the media.
