Phil, 

I am suspecting that MapServer is having a hard time using 
EPSG:42102.  Are you use it is listed in your epsg lookup file
for PROJ.4?  In cases where no reprojection is going on, 
declaring it might have cause no problem. 

I tried looking up 42102 with GDAL's EPSG lookup services
and found it was a cubewerx addition for BC Albers but for
some reason I had to comment out this particular coordinate
system because it was causing problems.  Perhaps this somehow
relates to your problem. 

Best regards,
