Samuele, thanks a lot for the report. Do you have a way to reproduce this crash?
Did you use search & replace? Do you have folded code in python?

You hit a corner case here we are trying to fix for a year or so, but do not have  a way to reproduce. So if you could help out here, that would be awesome.

Ouch!

Unfortunately I can not reproduce it.

I was editing a Python file containing diff conflicts (you know, thus 
resulting e.g. after a patch not applied correctly) and the syntax highlight 
was sometime invalid due to the presence of <<<<<<<, ========, >>>>>>> lines.

I was moving through the file while searching for the string "<<<" in order to 
jump from one conflict to the next one. And I was pasting a couple of lines of 
Python.

The code was fully unfolded.

But it happened only once.

Hope this helps.

Cheers!
