Update: I did experience the freeze WITHOUT the VirtualBox
As I am unable to save running applications' data after the freeze (see http://unix.stackexchange.com/questions/104011/how-to-recover-from-desktop-freeze-without-losing-running-windows) the bug prevents me from using the system.
Because there is no traffic around this bug report, I decided to abandon the Linux Mint 16... :-(
