Lowest object refuse snap to grid - "Only snap the node closest to the pointer" is ignored

[pRototype]

Inkscape 0.48.4 r9939 on Windows 7

Steps to reproduce:
* Open the attached svg drawing with Inkscape 0.48.4
* Select all objects (by drawing a rectangle around them). Make sure that ALL object is selected, also those outside of canvas.
* Grab upper left corner of the biggest rectangle (ID: rect4255) and move it around.
* Expected behaviour is that the corners of the rectangle snaps to grid. But instead the TEXT object (ID: text3155) closest to pointer will snap to grid, not the rectangle.

It is a undesired behaviour, but it's farirly easy to overcome. Workarounds that works for me:
¤ Delete all objects that is not inside canvas (works in this spesific case)
¤ Temporarly move the rectangle to top while moving, and move it bck to bottom when finished moving.
¤ Just using a develop version (t.ex Inkscape 0.48+devel r12042). Cannot reproduce the behaviour in that version.

¤ select ALL (96) objects with keyboard shortcut 'Ctrl+A' (instead of dragging a selection frame around them).

Likely related to the second issue described in bug #1093739, comments 8-10 (snapping a group of complex paths, convex hull and 'Only snap nodes closest to pointer').

No longer reproduced with current stable branch 0.48.x r9950: fixed in r9947 (backport from trunk)

With 'Only snap nodes closest to pointer' enabled in the preferences, one can snap the corners of the bottom rectangle to the grid while dragging the selection created as described -> 0.48.5 will have the same behavior as 0.48.3.1 and trunk.
