but in --quiet mode it fails with:<br>

Could you try to print tmp with and without quiet?<br>

it's just to get the length of the vector line for further calculations:<br>

in normal and verbose mode:<br>

as Moritz points out, it seems quiet mode suppresses the access to the<br>
output of grass.read_command; his solution/workaround with GRASS_VERBOSE env<br>
variable seems not to work here on my side.<br>
