Legend problem in MapServer 5.0

I have observed that legends do not work with existing mapfiles;  all of
which have MIN/MAX SCALES set.  It is broken using mode=browse, mode=legend
and GetLegendGraphics.  Little black boxes are returned for both GD and AGG
renderer's.  The same map, with the same extents has a working legend using
MS4.

See:

MS4: (working legend)

MS5: (broken legend)

http://pmap1.hud.uai.com/cgi-bin/mapserv.exe?map=/mapserver/gdt/main4.map&BBOX=-86.778940,34.651680,-86.718060,34.697320&mapxy=-86.7485%2034.6745&scale=24000.000000&layers=bound+hydro+landmark+roads+base_anno+hydro_anno+roads_anno+landmark_point+city&mode=browse

I do not have any mapfiles without MIN/MAX scales ready to test at the
moment.
