Internal server Error 500

[Stéphane RIFF]

Hi,

I have a problem on an application that display rasters.
When I zoompoint a an area where there is no rasters available I get an 
error 500.
This does not append when I make a zoom rectangle (I get a blank image : 
normal) !!!

Does somebody already saw that ?

I use mapserver 4.8

Thanks
