The crash :
Open elementary_test "genlist focus", click "genlist clear on focus".

The freeze :
Open elementary_test "genlist reusable contents". Click and item and then scroll down.
Here it freezes and I have to kill it.

Some other bugs:
genlist 7 : click the items, they get bigger and then you cannot click then anymore. I don't know if this is normal.
genlist reorder mode : if you reorder something, then the item is left empty. And then it crashes when you close the window. Also there is nothing to tell you, your long press is over.
