RE: [Inkscape-devel] Are these bugs?
I see. The reason for the difference is that the "Rect attributes" dialog shows you the raw SVG coordinates, while the top panel shows user corrdinates. The difference between them is typically a 0.8 multiplier (ask Mental about the origin of that multiplier, I'm not entirely sure) and the Y axis being turned upside down (for user, 0,0 is the lower left corner, but in SVG it's the top left corner). There were discussions about converging these two coordinate systems, but I'm not sure about the current status of that.
In any case, the "object attributes" dialog is more of a debug tool, it's not really intended for end users. We will nuke it as soon as we have all of its functionality (and more) in the top panel.

Oh please, otherwise you're gonna get a lot of people confused. ;)
Or, as you said you might do, nuke the object properties! ;)

I think we all decided it was a Good Idea but it never made it into the plan.

We're working on it. I consider the flipped coordinates a bug.
It was a decision made early in Sodipodi's development that is difficult to fix because the code that does it is spread throughout the codebase.
Nathan's been working dilligently on consolidating the coordinate inversion code in one place so we can cleanly fix it all in one shot.
