Mapserver crash when the text label from styleitem has some bracket in it

Hi,

using the STYLEITEM to have label and in the field there is this value:

LABEL(f:"Arial",t:"(N.3)",a:0,s:9g,c:#FF00FF)
I do some test and see that the point "." is not a problem .
Instead the problem seem to be the brackets.

I try to escape them using this sintax
<pre>
LABEL(f:"Arial",t:"\(N.3\)",a:0,s:9g,c:#FF00FF)
</pre>

but , if it has succes to avoi the crash of mapserver , unfortunatley in the text rendered
appear the "\" char.
:(

So I guess this is an issue.
