Fixed bug #292
...
I might be on crack here.
It looks like SDL_ConvertMono() in src/audio/SDL_audiocvt.c adds the left and
right channels of a stereo stream together, and clamps the new mono channel if
it would overflow.
Shouldn't it be dividing by 2 to average the two sample points instead of
clamping? Otherwise the mono sample point's volume doubles in the conversion.
This would also make the conversion faster, as it replaces two branches per
sample frame with a bitwise shift.

Fixed bug #329
...
On tracing it turns out to fail from SDL_WM_SetCaption()
On going through the function it looks like the SDL_free() function is called
every alternate time with an invalid pointer that has already been freed.
