It seems to me that the new fluidsynth is not that stable. I start
qjackctl which runs jackd (this is Fedora's jack 0.116.1-5) with
/usr/bin/jackd -R -dalsa -dhw:0 -r44100 -p1024 -n2 -Xseq
Then I start qsynth. As soon as I do this jack starts getting very
many xruns and in about 10 seconds qjackctl exits with a SIGKILL, also
killing jackd with itself along the way.

Now I start qjackctl once more and click on "Restart" on already
running qsynth. This time there are no xruns and jackd runs without

It's not desirable to use jack always with this workaround and I am
not pushing the package to stable until the issue is resolved.

Fernando, do you still develop jack? Do you know where the problem
might be? As soon as I downgrade to fluidsynth-1.0.8 these symptoms
