[Skand Hurkat]

Created boot partition (logical) on /dev/sda5
Created encrypted container on /dev/sda6

Created a new partition table on /dev/mapper/sda6_crypt
Created /dev/mapper/sda6_crypt1, format to ext4, mount as /
Created /dev/mapper/sda6_crypt2, use as swap.

Clicked next. Window for selecting time zone appears briefly before installer crashes.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We noticed that you were installing the LTS version of Ubuntu using an older version of the installation media. The latest point release of 12.04 is 12.04.4. Please try installing from that version of the installation media and see if that resolves your issue. Thanks in advance!
