Re: [Denemo-devel] music font patch

[Jeremiah Benham]

I am not sure if cvs is perfectly synced with the patches you created. I
just committed the RhythmKeymaprc because it seemed to be missing from
cvs. I don't know if their are other things off or not. Denemo refused
to compile until I added the RhythmKeymaprc. Now that I added the 
RhythmKeymaprc denemo compiles but segfaults on launch.

gdb is saying it segfaults here:
0x0807b1e5 in toggle_rhythm_toolbar (action=0x0, gui=0x80f4c98) at
view.c:897
897       if (GTK_WIDGET_VISIBLE (widget))

Here is a bt full:
