well, according to [1], SetSelection() should unselect item if n ==
wx.NOT_FOUND, it seems to me a bug in wxWidgets itself. Anyway,
location should contain at least one mapset (PERMANENT), so
SetSelection(0) should not fail because 'self.lbmapsets' contains at
least one item.
Module 'gis_set.py' (welcome screen) in releasebranch_6_3 uses
wx.ListBox for list of locations/mapsets, in trunk is used subclassed
wx.ListCtrl (to enable different style for mapset without user
permission). It is not backported to releasebranch_63 (missing
'g.mapset -l').
Please, try the attached patch, but it is just workaround... Helps?
