Muse Hub on Manjaro linux and muse-hub (binary) output to console

Background:
I've downloaded the Debian install file and converted it to an Arch User Repository package using debtap, which occurred with no errors. I then proceeded to install the AUR package on two different Manjaro GNOME machines, running the same version of Manjaro but with minor differences in installed packages and configuration.

Result:
muse-hub runs fine on one Manjaro machine and I was able to install all of the Muse Sounds. On the second machine, however, mus-hub fails silently, no output to the console whatsoever, also nothing in the journal about muse-hub, either, as well as nothing in the muse-hub log. On the machine on which muse-hub runs, there is a lot of output to the console, beginning with verifying that the user's language is English.

Question:
Does anyone have any suggestions on how to get some kind of information out of muse-hub on the non-working machine to troubleshoot it? With nothing in the application or system logs, or to the console, it's kind of impossible to know where to start.

Thank you!
