 A `~wxWindowBase(): any pushed event handlers must have been removed`
 error is generated using the following steps:

 1. Start GUI
 2. Add layers
 3. Save workspace file
 4. Start new GUI
 5. Open workspace
 6. Open workspace (again)

 I get the following traceback:

 {{{
 Traceback (most recent call last):
   File "/usr/lib/python2.7/dist-
 packages/wx-3.0-gtk2/wx/lib/buttons.py", line 140, in
 AcceptsFocus

 return self.IsShown() and self.IsEnabled()
   File "/usr/lib/python2.7/dist-
 packages/wx-3.0-gtk2/wx/_core.py", line 9984, in IsShown

 return _core_.Window_IsShown(*args, **kwargs)
 wx._core
 .
 PyAssertionError
 :
 C++ assertion "GetEventHandler() == this" failed at
 ../src/common/wincmn.cpp(478) in ~wxWindowBase(): any pushed
 event handlers must have been removed
 }}}

 This happens in trunk r70231 but not in 7.2.0.
