So if getSrate() ever returns 0 - you will always get a divide by zero
error.
replace soundsourceproxy.cpp line 79 with :
if (getSrate()) { pTrack->setDuration(length()/(2*getSrate())); }
Question is - why is getSrate() zero in this case (assuming that is
what the floating point exception happens to be)
