[Denemo-devel] Denemo fails to start

[Andreas Schneider]

Denemo fails to launch with the following messages:

   Gtk - WARNING : Locale not supported by C library.
                        Using the fallback 'C' locale.
(null) - WARNING : Couldn't register with accessibility bus: Did not
receive a reply. Possible causes include: the remote application did not
send a reply, the message bus security policy blocked the reply, the
reply timeout expired, or the network connection was broken.

I can remedy that by removing my .denemo-1.1.9 directory (i.e. after the
removal Denemo starts up). When I quit, Denemo hangs after the console
messages
Denemo - MESSAGE : That's it, I quit!
Denemo - MESSAGE : Destroying PortAudio backend

When I change MIDI settings, Denemo does not hang any more, but on quit
I get the console messages
Denemo - MESSAGE : Destroying PortAudio backend
Denemo - MESSAGE : Destroying PortMidi backend

Now I can redo my settings. But when the selected audio device is busy
or the order of the audio devices changes (which sometimes happens after
reboot for unknown reasons), Denemo again fails to start as in the
beginning and I have to remove my .denemo-1.1.9 directory again.
