hi, Varun
now i tried in another computer and the bug is present, the warning is
displayed.
maybe it is an OpenGL / VTK / WxWidgets bug ?
i also observed that python-vtk with wxpython has the same or similar bug:
having some vtk scenes in a wx.Notebook, and closing all pages, makes
application crash.
it does not crash when doing the same in a wx.aui.Notebook.

$ python /usr/share/doc/mayavi2/examples/mayavi/wx_embedding.py

(python:16598): Gtk-CRITICAL **: gtk_widget_set_colormap: assertion
`!GTK_WIDGET_REALIZED (widget)' failed
The program 'python' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 3089 error_code 9 request_code 136 minor_code 9)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
