Comment 30 for bug 1012629

It says fix released for trusty.. I'm installing trusty and experiencing same problem.
Getting a dialog that wants me to confirm the disk I've selected. Attaching a screenshot.
So apparently it's not fixed for trusty.

Here is my preseed partitioning snippet:

d-i debconf/priority string critical
