Hello,

Dapper Flight 5/6, noteedit 2.8.0-2:

$ noteedit

NOTE that this is an ex-Knoppix ex-Debian ex-Breezy now-Dapper install, so some upgrade issues might be the reason, but I think it's unlikely.

Thanks!

the same bug here. The solution: load module snd-seq or snd-seq-midi before running noteedit:
sudo modprobe snd-seq-midi
(Dapper is not loading this module by default!)
This will create /dev/snd/seq and noteedit will start without crashing.
Other problem is related in bug #38743
