[Bug]: Unsupported operand types when launching from shortcut

[nicolandu]

Describe the bug

When launching a program using a desktop shortcut generated by Bottles, a TypeError is generated and Bottles crashes. However, the same program can be launched from Bottles' GUI.

The output when the same command as the shortcut is run manually is available in the Troubleshooting Logs section of this bug report.

Contents of the .desktop file:

[Desktop Entry]
Name=NEXXT
Exec=flatpak run --command=bottles-cli com.usebottles.bottles run -p NEXXT -b 'Apps' -- %u
Type=Application
Terminal=false
Categories=Application;
Icon=/home/<username censored>/.var/app/com.usebottles.bottles/data/bottles/bottles/Apps/icons/NEXXT.png
Comment=Launch NEXXT using Bottles.
StartupWMClass=NEXXT
Actions=Configure;
[Desktop Action Configure]
Name=Configure in Bottles
Exec=flatpak run com.usebottles.bottles -b 'Apps'

To Reproduce

1. Create a new 'Applications' bottle.
2. Add a shortcut within the bottle to an EXE file.
3. Allow generation of desktop shortcuts using flatpak override com.usebottles.bottles --user --filesystem=xdg-data/applications.
4. Run the desktop shortcut: nothing happens.
5. Run the [Desktop Entry]'s Exec command. A TypeError is raised and Bottles crashes.

Duplicate of https://github.com/bottlesdevs/Bottles/issues/3210 and https://github.com/bottlesdevs/Bottles/issues/3226 and was fixed with https://github.com/bottlesdevs/Bottles/pull/3211. I guess the fix will be available in future release.
