Summary: wx.ToolBar.ClearTools() crashes OS X app in wxPython 2.8.4

Initial Comment:
This is a new bug for wxPython 2.8.4.  It is not present in wxPython 2.8.3.  It has been confirmed at two sites running OS X and using python 2.5.  It may exist on other platforms as well.

STEPS TO REPRODUCE:
1) Run the attached .py script.  It was derived from the ToolBar demo with the following lines added to TestToolBar.__init__():
        # ADDED TO TEST CRASH ISSUE WITH wxPython 2.8.4
        tb.ClearTools()
        tb.Realize()


Here is some info on the crash seen on OSX.

Hi all,

Any updates on a timeframe for when this fatal crash bug should be fixed?

We are frozen on using the 2.8.3 version (last good version) until this
recently introduced issue is addressed.

Many thanks,
Scot

No, it still crashes when ClearTools is called, and it looks like the
crash happens when it gets to a tool that is a wxControl.  I think that
what you fixed before was a different problem having to do with the
reference counting of control tools.  Here is the top of the stack:

0   <<00000000>> 	0x00000000 0 + 0
1   libwx_macud-2.8.0.dylib 	0x02123a90 wxToolBar::DoDeleteTool(unsigned
long, wxToolBarToolBase*) + 406 (toolbar.cpp:1683)
2   libwx_macud-2.8.0.dylib 	0x021d5d55
wxToolBarBase::DeleteToolByPos(unsigned long) + 189 (tbarbase.cpp:317)
3   libwx_macud-2.8.0.dylib 	0x021d62cc wxToolBarBase::ClearTools() + 36
(tbarbase.cpp:417)
4   _controls_.so           	0x10482a6f _wrap_ToolBarBase_ClearTools + 187
(_controls_wrap.cpp:24532)
5   org.python.python       	0x0020e278 PyObject_Call + 45

I think this one is already solved on WX_2_BRANCH, isn't it Robin ?

Best,

Would it be possible to bump up the priority on this one?  

We have an application that crashes with the 2.8.4 (latest version) so
cannot let people download the latest version of wxPython.  Preferably we
can keep everyone moving forward and on the latest wxPython version --
seems better for all.

Thank you,
Scot
