 IMHO, wxgrass should open a display window automatically if none is open
 and a map layer is added. Currently it gives this fairly cryptic error
 message:

 Traceback (most recent call last):
   File "/home/mlennert/SRC/GRASS/grass_trunk/dist.i486-pc-
 linux-gnu/etc/wxpython/wxgui.py", line 1145, in AddRaster

 wx._core
 .
 PyDeadObjectError
 :
 The C++ part of the Panel object has been deleted, attribute
 access no longer allowed.
