I think the particular problem you were encountering has been fixed in CVS
as of yesterday. Please try again. 

Short description: the code was converting some value to dB at one point.
You can't do this (you get -INF) if the value is 0, so the code was using a
large negative number instead. Too large.

In the particular case it was being used in, anything negative got clipped
to 0 about 2 lines later, so it didn't matter. The code now uses -400
instead. 

There may be other problems, but I think they've all been cleared up - let
us know (preferably with a backtrace of where things are dying) if anything
else breaks.
