[mapserver-dev] MS 6.0.2 bug

[Stephen Woodbridge]

I just got a weird error message:

msGetmarkerSize(): General error message. msGetMarkerSize() called on 
unloaded pixmap symbol, this is a bug in mapserver itself

Any idea what this is and how come we do not trap this condition and 
handle it in a benign way? Is this caused by having too many symbols 
defined?

This is easy for me to reproduce with this mapfile.
