Describe the bug
Integrating CPU-X app fails to extract its icon.
I am aware of a number of related issues with similar symptoms related to icon integration issues.
I am trying to track down why CPU-X does not fully integrate in particular compared to other apps.
I am looking for the source of WARNING: No icons found at "usr/share/icons" message.
No such or similar message was found searching AppImageLauncher and libappimage source code.
Where is this message coming from?
Expected behavior
App icon is extracted from AppImage and integrated in Ubuntu desktop.
Steps to reproduce the issue
- Download CPU-X AppImage: https://github.com/TheTumultuousUnicornOfDarkness/CPU-X/releases/download/v5.4.0/CPU-X-5.4.0-x86_64.AppImage
- Integrate using GUI or CLI
$ ail-cli integrate ~/Desktop/CPU-X-5.4.0-x86_64.AppImage
Processing /home/user/Desktop/CPU-X-5.4.0-x86_64.AppImage
Moving AppImage to integration directory

Additional context
I have mounted AppImages to inspect their contents. In fact CPU-X has more icons in usr/share/icons/hicolor/ than other apps. Please see the comparison screenshot below.
Available icons packaged in AppImage:
$ ./CPU-X-5.4.0-x86_64_e4591dac2df63c4871da4891ed34bd72.AppImage --appimage-mount

Please help me to track this down. It cannot be anything simple as dot in the filename, can it?
