I have opened a bug for this problem as I could not find one already. I 
also found another case that generates this problem on a polygon layer, 
if I uncomment the STYLE block in the LABEL below:

   CLASS
     EXPRESSION "K1231" # Hospital
     STYLE
       COLOR "#EBD2CF"
     END
     LABEL
#      STYLE
#        GEOMTRANSFORM 'labelpnt'
#        SYMBOL "etc/icons2/poi/8060.png"
#      END
       MAXSCALEDENOM 10000
       TYPE TRUETYPE
       FONT "sans"
       SIZE 8
       COLOR "#655949"
       OUTLINECOLOR "#F3EFEF"
       PARTIALS FALSE
       MINDISTANCE 250
       MINFEATURESIZE 10
       BUFFER 4
       POSITION AUTO
       PRIORITY 4
       WRAP " "
       ALIGN CENTER
     END
   END
