Comment 6 for bug 649940

@JazzyNico - with these steps I can reproduce it with Inkscape 0.48.2 and 0.48+devel r10747 on Mac OS X 10.5.8 (i396) too.

As far as I understand, this happens because the named file was never actually open in Inkscape (the current document window when closing inkscape is still 'New Document 1'). This seems to be the same as when saving a copy (instead of saving as): the copy is not added to the recently opened files because it was never actually opened in an Inkscape window.
