HTML legend not created in mapserver 4.6.1

[Vito Meuli]

Hi Jeff!

I'd really appreciate your help!

I'm sending you an archive with the most streamlined mapfile I can write that 
still reproduce my problem, along with the shapefiles and other stuff it 
needs to work (the mailing list will not get the attached file).
The mapfile is almos 400 lines long, so I'll post it on the list only if 
needed.

It seems that even if I modify a single character in the mapfile, the problem 
goes away!

Even the IMAGEURL seems to trigger the problem!
If I let it be 
IMAGEURL "/tmp/"
then the problems goes away!

It seems to be somewhat random...

The map file is named spancrazioPDF_modificatoVITOMEULI.map and I use a 
strange couple of files as templates, one for the map, template.xml, and one 
for the HTML legend, legenda.html. They are needed for a J2EE application 
that encapsulates Mapserver.

Normally I test the problem executing directly mapserver from the browser with 
an address like:
http://localhost/cgi-bin/mapserv-4.6.1?map=/varGIS/sanpancraziotest/spancrazioPDF_modificatoVITOMEULI.map
and I should get from the template a long list of text and tiny images that 
will go in the legend, like:

Instead, when there is the problem, I do not get the legend part, like the 
following:

-1.000000   -1.000000
---------------------------------------------------------------------

and no error message.

I get the same problem with the CGI-BIN mapserver 4.6.1 and 4.4.2.
No problem with 4.2.3 and 4.2.5, that unfortunately have other bugs.

I compiled mapserver 4.6.1 on a Red Hat Enterprise Linux AS 4, and I compiled 
all these libraries and programs:

zlib-1.2.3
proj-4.4.9 
libpng-1.2.8-config 
jpeg-6b
tiff-3.7.4
libgeotiff-1.2.2
freetype-2.1.10
gd-2.0.33
geos-2.1.4
postgresql-8.0.4
postgis-1.0.4
ecwsdk-3.1.25 (not compiled by me)
gdal-1.3.1
fcgi-2.4.0 
mod_fastcgi-2.4.2

The configure command was like this:

./configure \
--with-freetype=/usr/local/bin/freetype-config \
--with-zlib=/usr/local \
--with-png=/usr/local \
--with-jpeg=/usr/local \
--with-gd=/usr/local \
--with-proj=/usr/local \
--with-threads \
--with-geos=/usr/local/bin/geos-config \
--with-gdal=/usr/local/bin/gdal-config \
--with-tiff=/usr/local \
--with-postgis=/usr/local/pgsql/bin/pg_config \
--with-ogr=/usr/local/bin/gdal-config \
--with-wfs \
--with-wcs \
--with-wmsclient \
--with-wfsclient \
--with-fastcgi=/usr/local

I hope you can manage to discover the cause of this problem.

Thanks a lot!
Cheers,
Vito Meuli
