Thanks for the detailed analysis - could you attach such a sample (otherwise empty) SVG file? It would make a good test case for this issue.
The problem has been reported several times - Bug #499257 “saves svg file, that it can't read afterwards” is where most of the discussion was held so far. Linking your report as duplicate to bug #499257 - please add a comment here and revert the duplicate status if you don't agree and think these are different issues that need to be discussed and tracked separately.
