Hi,
When I am building enigma2 on Ubuntu (trusty) and trying to display menu (using spacebar) it crashes because of an assertion error.

self["menu"].updateList(self.list)
File "/usr/local/lib/enigma2/python/Components/Sources/List.py", line 102, in updateList
assert len(list) == len(self.__list)
AssertionError
So on Screens/Menu.py init we are starting with an empty list and then call createMenuList.
self["menu"] = List([])
self["menu"].enableWrapAround = True
self.createMenuList()
But on Sources/List.py we accept lists with the same lenghts!
def updateList(self, list):
"""Changes the list without changing the selection or emitting changed Events"""
assert len(list) == len(self.__list)
Of course when assert is comment out, menu is displayed without issues.
But, why we are not getting this problem on our boxes?
Since menu starts with [] and createMenuList adds the real menu elements, assert should always fail the first time!
Obviously it works on enigma2 receivers, but how? What adds values to __list between List([]) and self.createMenuList()?
