 Replying to [ticket:554 hamish]:

 you search in the description, not in the codes - so you get empty list.
 Use "Reload EPGS codes" to reload the list.

 > 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
 > }}}

 Fixed in r36775.

 result was found, and

 the 'search in desc' box is unusable until you press the Reload EPSG Codes
 button.

 Done in r36776.
