Linux/(Gnome?) File dialogs don't show an error if Zenity isn't installed

Game or games this happens in

None

What area of the game / PPSSPP

I'm using the latest commit on Fedora 41 Gnome
From what I've tested, if Zenity isn't installed, file dialogs don't show up or throw an error.
Everything works properly if Zenity is installed.
I haven't tested the QT version.

For example, the "Load..." button on the main menu does nothing.
The same issue applies to all of the load/save symbol buttons in the ImDebugger

What should happen

File dialogs should either display an error whenever Zenity isn't installed, or we should find a solution for file dialogs that doesn't require Zenity, eg modifying portable-file-dialogs or switching to a different library.

Whenever we decide what to do, I would be happy to fix it.

We actually already ask pfd if a file dialog is available, and we only show these buttons if it is:

return pfd::settings::available();

So it seems there's a bug in portable-file-dialog.

Could you point me to some file dialog library that would work on your system?

It's really annoying on Linux that there's no standard way to just pop a file dialog.

Ok, so the "Load..." button is working properly now ¯\_(ツ)_/¯ idk what fixed it between the last time I compiled and now.

I will research new libraries either today or tomorrow. If nothing promising comes up, would it be ok to make it clearer why the buttons don't work, eg greying out the buttons and adding a tooltip that says what's wrong?

The buttons in the debugger still don't work properly but that should be an easy fix.
