Right. The above handles that case, I believe. If the user clicks
with an empty string, showModal() returns wx.ID_OK, GetValue() returns
the empty string, db_name gets set to that empty string, db_name gets
tested (maybe I should have made the comparison with the empty string
explicit), the error dialog pops up since db_name is empty, and the
loop repeats.
