[vtkusers] VTK + wxPython + wx.aui X error

[Nicola Creati]

Hello,
I'm developing an application using VTK python (version 5.2.1) binding and
wxPython (2.8.9.2).
The main window frame is managed by wx.aui.
In the central panel there is a wxVTKRenderWindowInteractor (win1). In
another panel I create another wxVTKRenderWindowInteractor (win2). The
second panel (win2) is a float panel. If I try to dock the second panel
(win2) to the first one (win1) on Linux I get a X Window System Error and
the program close. The same program works perfectly under Windows.
I'm attaching an example script that reproduce the error:
Thank you.

Nicola
