The desktop file has an error:

gimp.desktop: error: value "?????????;?????????;????;??????;????????" for locale string list key "Keywords[mr]" in group "Desktop Entry" does not have a semicolon (';') as trailing character

Please test with a desktop-file-validate version that comes with Ubuntu 16.04 or earlier. Thanks.

Firejail related?

[sudo-give-me-coffee]

Apparently yes (netblue30/firejail#2690) the original GIMP does not run either

[probonopd]

Need to check like this:

sudo apt-get -y install make gcc libz-dev git
git clone https://github.com/plougher/squashfs-tools
cd squashfs-tools/squashfs-tools
make
strip unsquashfs
sudo mv unsquashfs /usr/local/bin

wget -c https://github.com/sudo-give-me-coffee/PhotoGIMP/releases/download/continuous/PhotoGIMP-x86_64.AppImage
chmod +x PhotoGIMP-x86_64.AppImage 
OFFSET=$(./PhotoGIMP-x86_64.AppImage --appimage-offset)
unsquashfs -o $OFFSET ./PhotoGIMP-x86_64.AppImage -ll /
# Need unsquashfs version with -o (e.g., compile from git)

Does it say

drwxrwxr-x root/root              (...) squashfs-root

like the working AppImages? Actually no, it says

drwx------ root/root               (...) squashfs-root

Why? Could it be that the permissions nor non-root users have been missing on the AppDir at AppImage creation time?

[sudo-give-me-coffee]

Done, now firejail --quiet --noprofile --net = none --appimage ./PhotoGIMP-x86_64.AppImage run perfectly

That's can be considered a bug of firejail? all permissions are set to rwxrwxr-x

[sudo-give-me-coffee]

By runnig with:

xhost +
sudo firejail...

Works but themes, open/save functions not work

No, and no:

me@host:~$ Downloads/PhotoGIMP-x86_64.AppImage /mnt --appimage-offset
188392

me@host:~$ sudo mount -o offset=188392 Downloads/PhotoGIMP-x86_64.AppImage /mnt

me@host:~$ ls -lh /mnt/
ls: cannot open directory '/mnt/': Permission denied

me@host:~$ ls -dlh squashfs-root/
drwx------ 5 me me 200 Jun 23 15:56 squashfs-root/
# This is wrong!

# Fix it
me@host:~$ sudo chmod -R a+rx squashfs-root

me@host:~$ ls -dlh squashfs-root/
drwxr-xr-x 5 me me 200 Jun 23 15:56 squashfs-root/
# This looks good

We don't recommend this anymore, users are pointed to appimaged or AppImageLauncher instead.
