Grid extension incorrectly handles transforms of parent group

confirmed on Windows XP, Inkscape build 10728.
although in my case the problem occurs only when the transform is on the top level layer, as would be caused by a page size change. If I have a translate operation on a subgroup as in the attached figure, then the grid appears to be correct.

I think your example shows a second bug (selecting a shape with a preserved transform). IMHO the position of both grids in your example is wrong: it should be placed on top of the bbox of the ellipse.

Attaching an example with simple rectangles inside a group.

hmm, maybe not - how did you create the grid outside of the group? By 'Ctrl-selecting' the ellipse inside the transformed group instead of actually entering the group?

Nevermind - I misread the file attached in comment #1-

As originally reported:

The difference is that you didn't enter the group - if selecting an object within a group without actually entering the group, the grid is placed correctly. But as with layers, the bug exposes itself if you first enter the group [1] so that it gets the current drawing level, and then apply the extension.

yes, I see what you mean. I duplicated the problem by double-clicking to get into the group, thanks for the tip. Previously I had selected the box using the XML editor.

Still repro.
