[Error] xargs parsing error at exporting app

[lrdass]

Describe the bug

distrobox-export --app emacs isn´t working as expected.
it throws the output:

xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option Error: cannot find any desktop files. Error: trying to export a non-installed application.

Trying to debugging it by setting only the folder /usr/share/applications it works properly.
So probably the bug is in one of the queries to find an emacs installation.

 xargs -t -I{} grep -le Exec=.*emacs.* -le Name=.*emacs.* {}

 xargs -t -I{} grep -Le Exec=.*/home/deck/.local/bin/distrobox-enter.* {}

 xargs -t -I{} printf %s@ {}

To Reproduce
Install emacs (ubuntu:latest):
sudo apt-get install emacs

and export it:
distrobox-export --app emacs

Expected behavior
Emacs exported to my local user.

Logs
(I've added the -t verbose tag to xargs to extend the grep command)

podman_log.log

Desktop (please complete the following information):

• Are you using podman, docker or lilipod?: podman
• Which version or podman, docker or lilipod? : podman version 4.5.1
• Which version of distrobox?: distrobox: 1.6.0.1
• Which host distribution?: SteamOS 3.5
• How did you install distrobox?: curl + prefix=.local/

Additional context
Context:
I have previously created a debian container and exported another application: VScode.
I had deleted the container (instead of removing the application first) - and the distrobox asked me to --force the deletion of the debian container.
This is the only correlation of cause that happened to this behaviour happen.

• I've deleted any shortcut previously setted ~/.local/share/applications, searched for any dead symbolic link to any shortcut for code.desktop.
• Debuged the export program, and it seems that it gets itself lost at some directory.
• Tried to reinstall every application: distrobox and podman -- no success
• Deleted the /etc/containers folder and re-downloaded the registries - no success
• I've also edited the directories for search the applications and have setted manually only to /usr/share/applications and it works properly. So my main idea is that during the search it finds an broken shortcut that returns a bad string that breaks xargs - probably a bad-link generated by the container that got deleted.

Found out what the problem was:
When xargs tried to find if it was already installed at ~/.local/share/applications, some of the games I had installed had a single-quote in the names.
This broke the xargs parsing, and exited as an error.

This issue can still be open to add a chage where it parses program that contains single quotes in the names.

I still get this issue and it prevents me from exporting apps

[AbduEhab]

This still is an issue it seems. I get the same error when exporting.

The problem was the apostrophe in a game's .desktop file name. Removing the file from the /home/deck/.local/share/applications/ directory solved the problem.
