wxAssertionError from wx.FileDialog in 4.2.5 only?!

1

With 4.2.5 on MacOS, I am seeing this error:

    if dlg.ShowModal() == wx.ID_OK:
       ~~~~~~~~~~~~~^^
wx._core.wxAssertionError: C++ assertion "nIndex < m_nCount" failed at ./include/wx/arrstr.h(227) in Item(): wxArrayString: index out of bounds

The code creating the problem is:

        dlg = wx.FileDialog(self, 'Choose GSAS-II project file name', pth, self.newGPXfile,
            'GSAS-II project file (*.gpx)|*.gpx',wx.FD_SAVE|wx.FD_OVERWRITE_PROMPT)
        if dlg.ShowModal() == wx.ID_OK:

FWIW, pth is an existing directory and self.newGPXfile is an empty str. This code has worked for many years. If I use conda to downgrade to wx 4.2.4, the problem goes away.

Anyone see anything wrong here or see a similar problem in 4.2.5?

This is a known bug in wxWidgets 3.2.9, unfortunately, see: wx.FileDialog regression in 4.2.5 · Issue #2860 · wxWidgets/Phoenix · GitHub

Thanks very much for letting me know. FWIW I did do some searching prior to posting, but did not find that issue.
