[mapserver-users] SLD with filter

[Yewondwossen Assefa]

Daniel,

  I just did a quick test with 5.6.x (svn) and a postgis layer using the 
metadata but could not reproduce a crash. If it is something I can 
reproduce using some test map/data/filter, I will investigate. You can 
either send them to me or attache it to a trac bug.

best regards
