It is actually very clearly visible in this - long - review: http://www.muktware.com/5194/kde-410-review-time-switch-kde. Just look at the first image, the gap between activity icon and dolphin is the pager.

Although I can see a bug in the current implementation, the pager should be considerably small (practically hidden). Right now it's just making the virtual desktop rect invisible and keeping the same size.

Oh it most certainly is on at least some level. Yes, if the pager is going to be hidden when one desktop is there, it shouldn't ghostily take up any room. But I don't think hiding the widget just because there is one desktop is a solution. In fact, I have seen users get confused around this, because their system is set to 1 VD and they add a pager widget, and what happens? Nothing. So they add it a few more times. Then they try adding it to a different panel, it still isn't working.

Turns out I had to tell them that they had to change the VD count to > 1, and surprise surprise! there's 20 pager widgets all over the desktop.

This is another case of someone trying to make something look clean and minimalistic, but not thinking about the consequences when it comes to user interaction.

If you don't like how the pager widget looks with 1 desktop, then don't ship it by default with 1 desktop, or don't ship the pager widget at all on a default desktop (which honestly I don't think many users(aka average) would use it in a default desktop).

Turning the pager widget into a ghost widget is definitely not the answer and we're going to get a lot of issues because of that, as I noted above, because I witnessed them first hand... Making it invisible really just pushes the confusion upward a bit more.
