Comment 6 for bug 151186

a workaround is to stop timidity manually:
sudo killall timidity

and afterwards run:
sudo apt-get install

then the package should finish installing cleanly and the really anoying mesages every update are gone.

For the package maintainer: The problem is that timidity simply starts itself. If it is already running(eg. on update) there is no point where the runing instance is stopped. So if you add a stop command just before the installation or right before the start command everything should without errors. I have no idea how to fix that with a patch or so but that should not be too hard to do.
