Not really. Like I said, sometimes I can "walk" the path and find where I
can insert or delete as normal. I do this at the same zoom level. It's like
the path got corrupted and I have to delete the corrupted part of the path
and rebuild it, then everything works fine again.

I'm wondering if my clipboard manager isn't screwing things up. I discovered
a problem within inkscape that is apparently affected by it and everything
works as it should when I turn it off.
Can you discern anything from this bug report that might affect gimp as
well?

I will try disabling my clipman next time and repeat the copy+paste to see
what happens.
