KDE does not mount / unlock LUKS-encryted DVD-RAM

[Hendrik B]

Problem:
I have installed a fresh Kubuntu based on Ubuntu 13.04. I have an DVD-RAM that contains a LUKS-crypto-container (crypto_LUKS) which in turn contains an UDF file system. When I insert the DVD-RAM in the device, KDE does not recognize that it is a LUKS encrypted device and, hence, KDE is not able to mount the UDF file system. It also does not display a dialog to enter the passphrase to unlock the LUKS crypto container.

To debug this to an extent, I have started "udisks --monitor-detail" to check if an event is generated to inform the KDE device notification system about the inserted DVD-RAM. The command displays these information:

According to the usage and type (crypto_LUKS), all information are available but the KDE device notification system does not seem to handle them. Please advice! Thanks.
