Still occurs ( c0d13df8537eade30e4781f2887caa808bbea440 ).
The memleak happens while cutting a single obstacle (the more you cut, the 
bigger the leak).

(somehow formatting got messed up)

There is no more memleak for obstacles, afaik.
Memleak with waypoints was fixed in commit 24c832f

There is still a memleak for items.
Other kind of objects have to be checked.
