[Qgis-developer] Mapfile Plugin

[John C. Tull]

Hi Borys,

I was intrigued by the new mapfile plugin, so gave it a test run this  
morning on a mapserver file I have. Unfortunately, it threw an error  
and was not able to load the layers. I cannot tell which layer is  
causing the problem, but even selecting a single layer from the list  
kicks out the same error. Any ideas on how to fix this? I'm on OS X  
10.6.1 and using William Kyngesburye's mapscript framework. Import  
mapscript from a python shell appears to load the module fine.

Here is the output:

An error has occured while executing Python code:
