Thanks a lot for debugging this up to that point! I somehow didn't notice this until fairly recently, and was puzzled (and frightened) at what it could be, yet didn't have time to dig in. And now I see you did, yay!
I don't see a problem re-asking for the line; although at some point I'll try and understand what changed in Scintilla that would lead to this.
