After commit 'Prefer color-scheme from...' generated AppImage won't start

[giuspen]

After the commit 'Prefer color-scheme from...' my generated AppImage won't start.

I had to peg my build script to the latest good version https://raw.githubusercontent.com/linuxdeploy/linuxdeploy-plugin-gtk/97290a3e374381e9fa7983ba098729a37076f3ed/linuxdeploy-plugin-gtk.sh as shown in giuspen/cherrytree@2827e3f

The thing is that nothing is printed at all on the terminal, it just does nothing (and nothing happens)

penoneg@cinnamon:~/git/cherrytree$ ./build/CherryTree-x86_64.AppImage 
penoneg@cinnamon:~/git/cherrytree$ 

While using the latest good version:

penoneg@cinnamon:~/git/cherrytree$ ./build/CherryTree-1.0.2-x86_64.AppImage 
[2023-09-28 21:11:44.619] [   ] [debug] /home/penoneg/.config/cherrytree/config.cfg parsed
...

Could you provide AppImages for A/B testing, please?

[giuspen]

Sure I will provide build logs and resulting binaries shortly

[giuspen]

The build logs are binary equivalent, the resulting binaries are not (A=master; B=97290a3e374381e9fa7983ba098729a37076f3ed):

https://www.giuspen.net/software/CherryTree-B-x86_64.AppImage

I am not able to reproduce this issue on my computer: both A and B start.
@giuspen can you run ./CherryTree-B-x86_64.AppImage --appimage-extract then bash -x ./squashfs-root/AppRun and provide us the output of last command, please?

[giuspen]

The failing one is A and its output is:

Well, it looks it was also buggy before anyway:

++ case "$(gsettings get org.gnome.desktop.interface color-scheme 2> /dev/null)" in
+++ gsettings get org.gnome.desktop.interface color-scheme

gsettings get org.gnome.desktop.interface color-scheme is exiting with an error code is this is not handled properly.

PR #58 pending approval.
