Grass wxpython gui won't start

[manuel.deljesuspe@…]

When launching GRASS, the starting window to select the map works fine. However, once the location has been chosen, wxpython gui fails to start. It throws the following error:

/opt/local/share/grass-6.4.2/etc/wxpython/wxgui.py:1614: wxPyDeprecationWarning: Call to deprecated item 'InitAllImageHandlers'.

wx.InitAllImageHandlers()
