About Ubuntu shows wrong version on Maverick 10.10

[ullgren]

When opening th About Ubuntu dialog (System -> About Ubuntu) on newly installed and updated Maverick is say
"You are using Ubuntu 11.04 - the Natty Narwhal - released in April 2011 and supported until October 2012."

However all the below indicated that it is indeed Ubuntu 10.10 Maverick.
ullgren@asi:~$ cat /etc/lsb-release
