-- Information about the crash:
- What I was doing when the application crashed:

python file, the same as before. (bug 294666).

1) Collapse a few bottom methods.
2) Get one above and delete/paste docstring text with last quotes """ that ending the docstring.
3) After that I collapse again below methods.
4) After repeated above, editor display all below text color is sillver as comments. Editor not recognize structure below this docsting, but structure is correct and docstring is closed.
5) Last step: Collapse that docstring generate crash.
