This isn't the most helpful bug report, since I can't reliably
reproduce it. But here's a recipe that *sometimes* works. (I have a
document in which it reliably works, but it's fairly long, and I can't
seem to find a way to cut it down to a minimal example: any cutting I
do eliminates the crash. Let me know if anyone wants to see the
document.)
Start with an empty document in book class. In a standard paragraph,
insert a note. In the body of the note, type some text, and make it be
a chapter heading (while leaving the paragraph in which the note is
embedded a standard paragraph). Then change the document class to
article. LyX-136 (sometimes) crashes.
It only happens, so long as I can tell, when the note with the chapter
heading in it is the first paragraph of the document.
Here's the output from gdb:
