[Qgis-developer] Mapserver Exporter Bug?

[Gary Sherman]

You should be using the latest mapserver exporter that is included in  
QGIS, not the plugin from the repository. Most of the problems you  
have encountered have been fixed in the latest version. Delete the  
$HOME/.qgis/python/plugins/mapserver_export directory and test again.

To avoid further confusion, I have removed the mapserver_exporter  
plugin from the respository. I will soon be releasing a standalone  
version of the exporter, complete with map preview and other features.  
It contains a number of fixes and enhancements over the current version.
