[mary-users] distorted sound with MBROLA voices

[Marc Schroeder]

Thanks a lot, Luzius, I have merged your fix into the bugfix branch and 
the trunk. Indeed the easiest at the moment is to submit reports and 
fixes via the mailing list; the TRAC settings are restrictive because we 
had just too much spam entered by robots.

Thanks again, best regards,
Marc
