 While trying to use the tool on a SRTM (N45E007), I was confronted with a
 segmentation and bus error. My mistake was inverting lat/lon...

 Here's my procedure to reproduce it.

 > r.horizon elevation=N45E007 coordinates=45.737698,7.361012 step=5

 {{{
 Note: In latitude-longitude coordinate system specify buffers in degree
 unit

 39437 bus error (core dumped)  r.horizon elevation=N45E007
 coordinates=45.737698,7.361012 step=5
 }}}


 > r.horizon elevation=N45E007 coordinates=45.737698,7.361012 step=0
 direction=215 bufferzone=1 maxdistance=5000

 {{{

 39574 segmentation fault (core dumped)  r.horizon elevation=N45E007
