Incidentally, I've noticed that when I open a file relative to my home directory in gedit (eg "~/project/main.c"), and then re-open that same file with an absolute path (eg "/home/bryan/project/main.c"), gedit thinks it's a different file & opens 2 copies.

Fortunately, the code that detects whether I've modified the file elsewhere still works fine, so it's never caused any major issues, just a slight annoyance every now and then. Might be different with Inkscape, though!

It's not the most common situation in the world, and probably not worth worrying about, but it does happen. In gedit, it usually happens because I open the file first via Nautilus, and then later on via the gedit command line extension.

Just thought I'd mention that!
