Happens only after I keep working for some time, on any random unodable action (move, scale, etc). After I rerun, reload and rerun the same actions, it works fine, only to crash again on some random action an hour later.

Ugh. Well, the basic problem is that the undo/redo notification callbacks _aren't supposed to be changing the document_. But checkForVirginity does sometimes, because it sets sodipodi:modified, and it tries to toggle undo sensitivity in the middle of what may be a not-yet-
Probably the simplest fix is to get rid of sodipodi:modified and replace it with a boolean field in SPDocument instead, which needs doing anyway.
