OK, I found the problem. Turns out I had left the textview associated with more
than one textstorage. I'm surprised that this was the only symptom. In detail,
when switching tabs in the editor, I forgot to remove the textview from all
other text containers before assigning it to the file associated with the new
tab. Silly.
