F6 panel grayed out

Usually when u add a object, say a sphere, you are allowed to press F6 or t, and then change the parameters in the panel. With build r37471M (recent build) that panel is all grayed out. Am i missing something, or is that a tiny glitch that has happened in a recent commit? Anyone have any suggestions?

Hm, work here with r37476M, i donĀ“t see any mails about changings in this area.
