 I think I've fixed this bug. Please test GRASS 6.5 svn R39213.

 It does not crash and display and zooming work in both constrained and
 unconstrained ("explore") modes. If you try repeatedly to zoom out beyond
 the maximum latlon (i.e., beyond 90N or 90S), the behavior is
 unpredictable. But it gives a clean error when it can no longer handle
 zoom out beyond what is permissible.

 Coordinates all seem to be accurate (i.e., the pointer seems to return the
 correct coordinate), and coordinates beyond 180E become West, and vice

 Please test. If it is satisfactory, it can be backported to 6.4.

 Note that it seems that the wxpython display does not seem to suffer from
 the latlon zooming bug, but functions pretty much as the fixed TclTk GUI
 does now. That is, it is unpredictable if you try to zoom beyond the
 maximum latlon, but otherwise works fine.
