Device not shown (text doesn't appear) in devices list

Description:

After upgrading to version 2.4, my Bluetooth loudspeaker not shows in list, but I can interact with it: when left-clicking, a drop-down menu appears (e.g. "Rename" is selected):

Installing the gnome-icon-theme package completely removes all errors, but this package is from AUR (and its dependent package gnome-icon-theme-symbolic too)

I've already talked to the blueman developers, where we found out that the main python script doesn't load the image file /usr/share/icons/Adwaita/symbolic/devices/audio-card-symbolic.svg as it should, but all files are represented on the system.

Additional info:

• package version(s): 2.4-1
• config and/or log files: blueman.log
