Thank you for taking the time to report this bug and helping to make Ubuntu better.
If there is a bug here, it is mostly likely in phpmyadmin rather than debconf or mysql-5.5, so I'm rearranging the assignment accordingly.
But I could not reproduce this on the current version of Quantal. I followed your steps, except that on step 7, it worked. Please could you retest your steps on a fresh, fully upgraded installation of Quantal, and confirm that your exact steps do reproduce the problem? Once done, please change the bug status on phpmyadmin back to New.
