Comment 5 for bug 1288272

If it is as expected, then the bug is in the snap bar. In the document properties there are three settings for snap:
1) Snap to objects.
2) Snap to grids.
3) Snap to guides.

In the snap bar, there are the following related settings:
A) Enable snapping.
B) Snap to the page border.
C) Snap to grids.
D) Snap to guides.

Disabling A disables the options B-D. I'll assume that C <=> 2 and D <=> 2. What is B (page border)? Is it an object? What other items are considered "object"?

I believe there are two possibilities:
#1) Add an additional toggle button "snap to objects" to the snap bar, and add "snap to page border" to the document properties.
#2) Change "snap to page border" in the snap bar to "snap to objects".
