This bug was reported and fixed by Sebastien Morin (sebastien dot morin dot 1 at ulaval dot ca) by
the patch 'patch__specific_fns__jw_mapping__l1.3_r3342' attached to the bug report.
In the 1.3 line, revision 3342, there is a typo in the 'set()' function of the file
'specific_fns/jw_mapping.py'. The string 'csa' is used twice on line 398. The string 'csa' should
be used first and, then, the string 'r'.
