solfege not working

[frankyD]

Binary package hint: solfege

launching solfege gives:
~$ solfege
Checking for gtkhtml2... ok
warning: invalid directory in path: /home/fda/lessonfiles
Solfege will use fakesynth
/usr/share/solfege/src/mainwin.py:436: GtkWarning: Refusing to add non-unique action '_Rhythm' to action group 'NotExit'
  self.m_action_groups['NotExit'].add_actions(actions)

Traceback (most recent call last):
  File "/usr/bin/solfege", line 77, in <module>
...etc.

apparently it's fixed in 3.10.1 (is now 3.9.3 in Hardy Heron) according to this link:
http://www.solfege.org/SITS/00167

so, an update perhaps?
