I log this bug only to take a record.  Right now I tried to load a local SLD
without success.  Chris maybe you could try that.

Steps to reproduce:

1.  Load "sample_ogc.phtml"
2.  Click "OpenSLD" button
3.  Click "Browse" button
4.  Select "sld_line_width.xml" local SLD 
5.  Click "Apply" button
6.  No SLD is applied to  "WorldGen_Outline" layer

No error message at all.  Maybe I'm doing something wrong but could not see what
it is right now.

Similar results with URL:

Instead of loading the SLD file directly, load the SLD by specifying the URL:
http://127.0.0.1/nsavard/sld/sld_line_width.xml
http://localhost/nsavard/sld/sld_line_width.xml
http://192.168.4.100/nsavard/sld/sld_line_width.xml


I tested the SLD directly with MS in a browser and it works as expected:

samples/map/world_wms.map&service=wms&version=1.1.1&layers=l2:WorldGen_Outline
