QML cannot open file dialog

I am trying to create a simple dialog using QML:

import QtQuick 2.2
import QtQuick.Dialogs 1.0

FileDialog {
    id: fileDialog
    title: "Please choose a file"
    onAccepted: {
        console.log("You chose: " + fileDialog.fileUrls)
        Qt.quit()
    }
    onRejected: {
        console.log("Canceled")
        Qt.quit()
    }
    Component.onCompleted: visible = true
}

      

        
        
        
      

    

However, when I try to view it, I get the following errors / warnings:

QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such file or directory
Invalid URL:  QUrl( "" ) 
Invalid URL:  QUrl( "" ) 
Invalid URL:  QUrl( "" ) 
Invalid URL:  QUrl( "" ) 
kf5.kio.core: KLocalSocket(0x1a51cf0) Jumbo packet of 35946 bytes

      

        
        
        
      

    

As far as I understand, the QUrl settings are not needed to display the dialog. If so, is it possible to install it to the user's home folder in a cross-platform way? I also tried to start the ibus daemon as I found on google that it throws the first line of errors, but it still doesn't work.

I am using Arch (fully updated) with KF5 and QT5.4 installed.

Thanks for the help!
