 Hi Community,

 I wanted to use r.thin on a raster map before r.to.vect on the result 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. The following
 error is printed to the console.

 {{{

 Any Ideas what might be going wrong?

 The output of g.versoin -rge

 While this should probably be handled more gracefully, could you explain
 what you are trying to do with r.thin ? Why would you run r.thin on a DEM
 ? r.thin is meant to thin raster lines (represented by some form of
 discrete pixel values) to single pixel width so as to make their
 vectorisation possible. Running it on a raster map with a continuous
 variable doesn't make sense in my understanding.

 The download inscructions for Ubuntu mention:

 # 1.b) Users of non-LTS release (like Ubuntu 17.10): Add GRASS Stable PPA
 sudo add-apt-repository ppa:grass/grass-stable

 However, the grass-stable ppa does not contain 7.4 packages and does not
 contain files for artful.

 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.

 New in trunk, does not apply to 7.4-, thus fixed.

Comment (by wenzeslaus):

 Note that `sys.version_info.major` is at more places.
 `sys.version_info[0]` works all right in 3, but in general I'm not sure if
 we can maintain 2.6 compatibility while using 3
 (https://docs.python.org/3/howto/pyporting.html#drop-support-for-
 python-2-6-and-older).
