 wxgui crashes when setting the color table from layer manager

 To reproduce
 Load a raster layer
 RClick on layer -> Set color table

 This will hang the ui for some time and prints a bunch of errors on the
 terminal

 (wxgui.py:26033): Gdk-CRITICAL **: IA__gdk_gc_set_foreground: assertion

 Interestingly the error appears only for those maps created using
 r.composite
 To reproduce on your own try landsat avaialble in nc_spm_08/landsat

 r.composite red=lsat5_1987_40 at landsat green=lsat5_1987_30 at landsat
 blue=lsat5_1987_20 at landsat output=rgb

 Load the new map rgb and try to set color table from gui
