Some desperate debugging later ... 
Seems like denemo just segfaults (now: why don't I see this at the shell prompt?
Is someone really catching signals?). 
Stacktrace is here:

 Program received signal SIGSEGV, Segmentation fault.
 [Switching to Thread 0xb687f730 (LWP 19947)]
 jack_output_midi_event (buffer=0xbfe7e44b "ð\177\177\b\b\003\177\177", '@' 
<repeats 12 times>, "÷", client_number=0, port_number=0)
    at jackmidi.c:187
 warning: Source file is more recent than executable.
 187      DenemoScore *si = Denemo.gui->si;

 (gdb) print Denemo.gui 
 $1 = (DenemoGUI *) 0x0

Dereferencing this like here ' DenemoScore *si = Denemo.gui->si; ' of course 

BTW - why does denemo try to set/change the tuning _during startup_???

 #1  0x0808a9d2 in change_tuning (cents=0x81653c0) at midi.c:135
 #2  0x0810a64f in set_tuning () at pitchentry.c:1103

That's a nuisance at least. Keep of my keyboard unless i ask you for it.
(And it's silly on so many levels: midi might not be connected, my excellent 
simulator (Aeolus) doesn't care about tuning messages ....).

 Cheers, RalfD
