[Denemo-devel] Denemo crash

[Andreas Schneider]

On a Debian Jessie with KDE, Denemo 1.2.2 crashes with "Attempt to
unlock mutex that was not locked" even at the first launch (after the
question whether to re-use old settings, which I answered no):

fluidsynth: warning: Failed to pin the sample data to RAM; swapping is
possible.

Maybe this is connected with arts using the devices?

A similar crash occurs with the version 1.1.8 shipped with the distro.
