Have been digging a bit more on this problem.

In wx.lib.aui.framemanager.py from about line 6226 we have this:

         # delete old sizer first
         self._frame.SetSizer(None)

         # create a layout for all of the panes
         sizer = self.LayoutAll(self._panes, self._docks, self._uiparts, 
False)

If self._frame is a sizedControl this removes its sizer which then 
causes the above error.  self.LayoutAll is creating a new sizer which 
later on will be used for self._frame.SetSizer(sizer) but it is too late 
if control is a sizedControl.

Any tip on how I should go about to come up with a patch for this?

Ideally AUI should leave the sizer(s) managed by SizedControl alone, 
especially as AUI uses a BoxSizer when creating the new sizer which 
might not be what was used in the SizedControl.
