Nope, that's apparently not the problem. I tried by just removing the 
newline between the two lines, and I still get:

Traceback (most recent call last):
   File "/usr/lib/grass/etc/wx/wxgui.py", line 444, in addRaster
     self.SetTree('raster')
   File "/usr/lib/grass/etc/wx/wxgui.py", line 487, in SetTree
     self.maptree.AddLayer(disp_idx, layertype)
   File "/usr/lib/grass/etc/wx/gui_modules/wxgui_utils.py", line 151, in 
AddLayer    if (self.layer_selected and self.layer_selected != 
self.GetRootItem() and self.layertype[self.layer_selected] != 'group'):
   File 
"/usr/lib/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/_controls.py", 
line 4996, in __ne__
     return _controls_.TreeItemId___ne__(*args, **kwargs)
TypeError: in method 'TreeItemId___ne__', expected argument 2 of type 
'wxTreeItemId const *'

Sounds more like a wrong data type being sent to a method...
