Summary:                    [patch] MusicOnHold produces a crash
Description: 
MusicOnHold produces a crash on hangup when class configured in realtime
refers for non existing or an empty directory.
And this only happens when using cachertclasses flag in musiconhold.conf.
I made a patch for fixing this issue.

I uploaded a different patch I would like testing with.  If I'm
understanding things correctly, I believe my patch will more clearly
resolve this in the code.   If the mohclass is present at the end of this
function, it has it's refcount decremented.  If MOH_CACHERTCLASSES flag is
set it is possible the refcount was never incremented in the first place
which could cause a crash.
