 but r.thin crashes after 84 passes every time. Smaller number of
 iterations run without any problems. I was able to reproduce the error by
 using r.thin on the elevation.dem from the Spearfish data set.

 On the OS command line
 g.region -p rast=elevation.dem
 r.thin in=elevation.dem out=elevation.dem.thin it=1000
 finishes successfully after 229 passes.

 Apparently the problem is that the gui can't handle the messages produced
 by r.thin, i.e. the gui crashes, not r.thin.
