I think you might have misunderstood my post slightly: I do not normally have non-square icons on the dock. My clock icon was equal in height and width until the upgrade, but bigger than the other icons. After the upgrade, it became oval -- width was retained but height was constrained.
(However, with the bug, my switcher icon on the dock now also has non-square proportions, but I like that! It shows widescreen desktops more similar in shape to the full-size screens.)
I'll attach a couple of screenshots. They're from different machines, one upgraded and one not. The docks aren't set up identically, but I hope it will show the difference.
I will give the BZR version a try.
