Bug Description

- running Windows XP, Inkscape rev 14146, with mm as the default document unit
- load the Document Properties dialog and run Nup layout extension.
- in the Nup layout Page Dimensions tab, set units to mm and set size to 210x297 mm
- apply extension and check the Document Properties to note that the new page size is given as 210*297 px, not mm
- restart Inkscape with same document and rerun the Nup layout.
- choose a Nup layout page size of 816*1056px in order to produce a standard letter size page.
- check the Document Properties dialog to see that the new page size is actually 215.9*279.4 px, which is too small

- not reproduced if the startup document is default_px.svg which uses px as the document unit.

Reproduced with Inkscape 0.91+devel r14146 on OS X 10.7.5.
