Ya I see what you're talking about.
I can fix it in SkinStudio. It looks like if you want to be able to line it up with either small or large user icons you'll want to create a separate substyle for the small ones.
Need to change: [Edit Startmenu and Taskbar] [Edit Start Menu] [All programs] [Background] [Text] [Left] from "-100" to "-80". The "-80" might depend on the screen resolution you run, not sure.
Here's a link to a screenshot, couldn't seem to get it in here (looks like ImageShack may have gotten a little pop-uppy, probably want to dodge those):

Edit - I'll take that back, the "-80" seems to work ok for the large icons too. (What do you expect from a guy who suddenly can't get a screenshot to work
)
