Comment (by annakrat):

 I still can't reproduce it, even with wxpython 3.0.2.0. First try using
 different font, but I don't think that would help. Next try to apply this
 change and recompile:

 {{{

  def RenderText(text, font, bgcolor, fgcolor):
      """Renderes text with given font to bitmap."""
 -    dc = wx.MemoryDC()
 +    dc = wx.MemoryDC(wx.EmptyBitmap(20, 20))
      dc.SetFont(font)
      w, h = dc.GetTextExtent(text)
      bmp = wx.EmptyBitmap(w + 2, h + 2)

 }}}

 I hope this could help, otherwise I have no idea.
