Details:

Denemo 2.5.1 64-bit AppImage does not start on my desktop PC.

OS is LinuxMint 18.3 64-bit version with Xfce desktop environment.

The AppImage file is marked as executable. Cannot find any information on the
internet on what needs to be done to correct the problem.

Messages in terminal follow:

------------------------------------

This problem is similar to bug #59547: Denemo does not start.

I followed the instructions in rshann's last comment to edit the denemorc XML
file and the results are below the referred comment in the bug report.

"Thu 10 Dec 2020 11:50:44 AM UTC, comment #10: 

Thank you for the debug output. From this it is clear that opening the default
output audio device (and/or the input MIDI device) causes the ALSA library to
crash.
In this circumstance the only way to choose an audio output device is to edit
the file
~/denemo-2.4.5/denemorc

at the line 72

    <portaudio_device>default</portaudio_device>

to become

    <portaudio_device>none</portaudio_device>

As a precaution, it would be good to also disable the MIDI in device line 76
to become

    <portmidi_input_device>none</portmidi_input_device>

with these edits, the program should start and it would be possible to choose
from the Edit menu

Edit->Change Preferences

at the Audio tab the output device that works (if any!).

The program will work without audio, but it is easier to use with audio
feedback.
If you can report back on the behavior with this startup file I would be very
grateful."

Please let me know if any more information is required. Other than compiling
from source code, I should be able to follow other instructions.
