Comment (by mmetz):

 Replying to [ticket:3335 pvanbosgeo]:

 The problem appears when a label is assigned to a range of values, e.g.
 {{{
 992:996:Morrisville
 }}}

 this means that all raster values from 992 to 996 should get the same
 label "Morrisville". The raster library supports writing such a range of
 values for all map types with Rast_set_cat(), but reading such a range of
 values is supported only for fp maps (FCELL, DCELL).

 Please try trunk r70900.
