Retesting the affected file with r12721:
It seems that it only happens once per session - the fist time the document properties dialog is opened.
Workaround:
1) launch inkscape
2) open & close the document properties dialog
3) open the affected file
--> now nothing happens when opening document properties again.
However, changing the document units still produces unexpected results (drawing content is scaled differently relative to the page size) - see also comment #5 in bug #1239682.
