Comment (by wonder):

 Replying to [comment:3 msieczka]:
 > Not sure if that's relevant, but what are your snapping options? Do you
 rely on snapping settings from the general 'Options' menu or do you set
 them for that given layer in project properties? If the latter, do you
 also set 'Topological editing' and 'Avoid intersections'?

 I use general snapping options, no topological editing, neither avoid
 intersections. But shouldn't really matter, the crash is somewhere deep
 inside splitting routines.


 > Can you post a backtrace?
