Changing property layout of a list property in a class doesn' work (multiple select yes/no)

When you add a list property, whatever it's a static list or database list, you can't modify the layout it's displayed.

How to reproduce :
1) create a class, add a property list (static list or database list, bug on both but static is more simple for trying)
2) select No on multiple select
3) save your class
4) create a new doc from this class
5) go back to class editor and change property layout form No to Yes
6) save your class

Wiki crashes.
This has been tested on both static and db list and both reversing form No to Yes and Yes to No on Multiple select.

Exception Error should look like this (has you can guess, my static list was "choice 1|choice 2|choice 3|choice 4|choice 5" :
Error number 3201 in 3: Exception while saving document Main.TestAlexDocA
Wrapped Exception: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.xpn.xwiki.objects.StringListProperty#
