[GRASSLIST:2917] r.thin works inverse (GRASS5)

as I tried to thin my raster map (imported from tif file with white background
and black drawings) r.thin created a thined raster map of the inverse source.
All white areas became thin red lines on yellow background, how can I
configure r.thin to thin all linear components of my black drawings and to
keep my white background?
