Ubuntu Server 14.04.2 installer hangs on man-db (amd64) configuration

[Damiön la Bagh]

When installing Ubuntu Server 14.04.2 in a VirutalBox virtual machine the installer hangs on man-db (amd64) configuration.

Steps to reproduce the error:
Set up a VM in Virutalbox with the following settings (see attachment for details of the VM)

4GB RAM
2x VDI virutal drives (8GB & 16GB)
VideoRAM 128
NAT network
90% CPU execution cap

Install Ubuntu
*Encrypted LVM on the first drive
** (weird that you can't choose both drives in the installer, but that's besides the point)
SSH
LAMP
MAIL

Ubuntu Server starts installing but when it gets to man-db (amd64) is being configured the entire installer hangs to a complete lockup. (see the kernel trace on tty5 attachment and the screenshot of the installer hang)

What should have happend?
- The installer should have finished and reboot so I could continue to configure my system.

Here is a screenshot of the last available data from TTY5 showing what looks like a Kernel error.

Here is the live syslog during the installer (was able to extract it mounting a USB stick attached to the virutal machine on TTY1 busybox)

the syslog from the actual install (with attachment now Launchpad is so unfriendly for uploading proof)

here is the partman from the actuall install

Here is the actual media-info file from the installer
Ubuntu-Server 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1)

Now 6 months further, using installer 14.04.3 LTS and this bug still exists. I am able to reproduce it with the exact same installation method. Using the latest version of Virtual Box (Windows 7 - 64-bit host).
