My browser shows:"


  CGI Error

The specified CGI application misbehaved by not returning a complete set 
of HTTP headers. The headers it did return are:"

and a message box with title "mapserv.exe - Application Error" shows 
"The instruction at "0x101c7e24" referenced memory at "0xcccc1033". The 
memory could not be "read".
Alas, no service exception report.

The native projection is the same as epsg:28992 which is declared in the 
PROJECTION block for that layer and for the map. (see the end of this 
e-mail)

I did try this, but is doesn't make a difference.

I read the same in the wms specification. Should a bug report be filed 
for this? Although there are already  5 entries when searching for srs 
(but none for this problem).
