It's huge, I don't want to waste any more of your time on this as I'm happy adding that one extra line immediately after saving the QDialog. It's a personal Editor plugin so no-one else is affected.
If I can reliably reproduce it in a small test plugin I'll post again.
In the meantime I think maybe there's a bigger problem in the Editor. I just updated my run-from-source copy. I can no longer run a regex search in the Editor. This is the error message:
