Thanks Robert.

The first bug was probably due to the incorrect formula for the mean of 
the triangular distribution.  That has been fixed (it should change with 
different loc and scale parameters).

The second ppf bug affected all distributions (it was in the base 
class).  Thanks for finding it.  It has been corrected.
