Expected Behavior

If cannot use the trash, the system should warn the user and let him/her decide what to do (whether to delete permanently or not to do anything).

Current Behavior

When your .var directory is a bind mount the system has no trash. In native (not flatpack) applications like Nautilus the system is aware of this and when you are going to delete a file it alerts you to this fact.

For example, in an application like Workbench when closing a project and discarding it, the program tries to send it to the trash giving this error (and as a result the window cannot be closed).

Steps to Reproduce

1. Mount a drive in any directory, for example /mnt.
2. Create a subdirectory /mnt/myvar.
3. Bind mount /mnt/myvar as your ~/.var directory.
4. Install workbench.
5. Open a project.
6. Try to close it discarding changes.
7. Profit 😂

Anything else we should know?
