When I install Feisty and I choose to do Manual partitioning, there is nothing that Ubiquity does to tells me why I cannot add a new partition in the free space. I already have four primary partitions defined so of course I cannot add another partition. However, unless I already knew there is a limit of four primary/extended partitions, I would think that the "Prepare partitions" was broken because when you double-click on the "free space", nothing happens.
How to recreate:
Launch Feisty LiveCD install,
In "Prepare Disk Space" step, select Manual partitioning.
Add partitions until there are four primary partitions defined, leaving some "free space" yet.
Double-click on the "free space".
Instead of getting the "Create partition" dialog box, nothing happens.
Expected behavior:
If I try to add a fifth partition, maybe display an error message to tell me that there is a limit of four primary partitions, and that to get more partitions I can go with three primary partitions and then add logical partitions from there?

As a frequent visitor/contributor to Ubuntu Forums, I can see this generating a lot of new user posts.
An example of how this could happen.
User has XP, and shrinks partition. User reads that a fat 32 partition should be used to share files. User reads that a /boot partition should be first so the system can boot large drives. User creates /, and hits 4. Now user attempts to create swap, and fails. User posts to Ubuntu Forums about how everyone is a jerk. :)
