[v3 bug] application.OpenFileDialog() is broken in Linux

[micahflee]

Description

When I try opening a file selection dialog, it works as expected in macOS and Windows, but it crashes in Linux after selecting files.

To Reproduce

Create a new wails v3 project by running:

wails3 init -n myfirstapp

Edit greetservice.go to try opening a file selection dialog in the Greet function:

package main

import (
    "strings"

    "github.com/wailsapp/wails/v3/pkg/application"
)

type GreetService struct{}

func (g *GreetService) Greet(name string) string {
    paths, err := application.OpenFileDialog().
        CanChooseFiles(true).
        CanCreateDirectories(false).
        AllowsOtherFileTypes(true).
        ShowHiddenFiles(false).
        PromptForMultipleSelection()
    if err != nil {
        return "There was an error!"
    }
    return strings.Join(paths, ",")
}

Run the app with wails3 dev, type in the field and click Greet, and it pops up a file selection dialog. Select a file. It crashes with the following in the terminal:
