1. Add a raster map (raster or vector).
2. Zoom in until an error like this pops up:
{{{
Execution failed: 'd.rast [EMAIL PROTECTED] --q'
Details:
ERROR: region for current mapset line 1run "g.region"
}}}
3. Try to "Zoom to selected map" or any other zoom operation - a
crash:
{{{

Arrgh. Fixed this in TclTk but seems like we need to fix it in
wxPython too. Thanks for spotting it. With new graphic tools in
wxpython, Glynn's rewrite of the display drivers, and Martin's work on
nD visualization we may be reworking the display rendering engine. At
the moment, I'm not sure how much will be back ported to wxpython. We
might try a simple patch on this for the moment, however. I'll try to
look into it.
