If I delete the displayed date in a GenericDatePickerCtrl window, and
tab or click out of the control, it crashes with the following error:

wx._core.PyAssertionError: C++ assertion "dt.IsValid()" failed at ..\..
\src\msw\calctrl.cpp(262) in wxCalendarCtrl::SetDate(): invalid date

However, if I catch the DATE_CHANGED event, the crash does not occur.
The code below demonstrates the problem, where picker1 and picker3 do
not catch the event and do crash; picker2 does catch the event and
does not crash.

What's going on here?

Try with 2.9.3.1, your sample code worked okay for me with that version.

The AuiNotebook is now derived from BookCtrlBase instead of reimplementing all the basic functionality itself. AddPage in BookCtrlBase looks like this:

     virtual bool AddPage(wxWindow *page,
                          const wxString& text,
                          bool select = false,
                          int imageId = -1);

There is still the AddPage in AuiNotebook like the following, but apparently the one in the base class is taking precedence there...

     bool AddPage(wxWindow* page,
                  const wxString& caption,
                  bool select = false,
                  const wxBitmap& bitmap = wxNullBitmap);

Robin,
     Many thx for the reply.
     Several things:

1. 2.9.3.1 indeed seems to fix that problem.

2. However, 2.9.3.1 breaks the .AddPage method of AuiNotebook. The
statement:
         self.auinbDataLists.AddPage( self.pnlAllVehicles, u"Vehicles",
False, wx.NullImage )
     works in 2.9.2.4 but in 2.9.31 generates this exception:
       TypeError: in method 'BookCtrlBase_AddPage', expected argument 5
of type 'int'

     If I eliminate that last argument (wx.NullImage), it works. (FYI,
I think FormBuilder creates the wx.NullImage argument.)
