 Hi,

 in the latest 6.4.0svn wingrass build from osgeo4w--

 - startup with wxgui.
 - Define new location via location wizard.
 - by epsg code (list comes up now, great to see that fixed!)
 - Search in description: ___ something with no hits, eg 4326 or typo

 At this point the list of codes is empty and the following error message
 appears on the DOS console window:

 {{{
 Traceback (most recent call last):
  File
 "C:\OSGeo4W\apps\grass\grass-6.4.0svn\etc\wxpython\gui_modules\location_wizard.py",
 line 1365, in OnSearch
     self.epsgcode = self.epsglist.Search(index=1, str=value)[0]
 TypeError: 'NoneType' object is unsubscriptable
 }}}


 so I guess two things are needed:
 - only try to grab epsg code to fill in "EPSG code: ____" box if >=1
 result was found, and
 - automatically reload EPSG codes before each new search (if 0 hits then
 the 'search in desc' box is unusable until you press the Reload EPSG Codes
 button.


 thanks,
 Hamish
