Crash (4.0c B2): Ctrl-z with hyperlinks in notes

When I am in a note file and type a Bible reference and then press space it automatically tags it as a hyperlink. If I hit backspace it removes the hyperlink and makes it regular text.  However, I did this accidentally and instinctively hit Ctrl+z trying to undo the deletion of the link.  Then Logos crashed.  It's totally reproducible: open a note, type a Bible reference, hit backspace to clear the link, then hit Ctrl+z.  See attached logs (tried in different note files).

I was trying to see if it happened when you select Undo from the menu instead of just using the keyboard shortcut, but another interesting thing happens.  If you put the cursor at the end of an existing Bible reference and then hit backspace to clear the link then click on the Note icon in the top left to bring up the menu with Undo, etc., the link is restored.  That is, you backspace to clear it and it comes back when you click the menu.  It doesn't happen if you move the cursor again before clicking the menu.

THANKS, by the way, for the improvements/bug fixes in the automatic reference linking.  They're very helpful.
