vertices as close as 0.0001 degrees. However, v.clean only
removes vertices at threshold values of about 50 or up. This
seems to suggest that the tools assumes threshold values are
in meters?<br>

a bug, an error in the manual page (i.e., threshold values
are not in mapping units, but in meters like for the rmarea)
, or I am doing something wrong (note that it seems to work
fine if one assumed threshold values have to be in meters).
If a bug or error in the manual page, I can create a ticket.<br>

</div>
It's a bug in the code [0], the algorithm is not working
properly. There is v.generalize, therefore I recommend to
remove the prune tool from v.clean.<br>

+1 if it doesn't work properly and it is a won't fix better to
remove<br>
