Folder dialog returns incorrect URL when used to select a folder whose name ends with a trailing space

The standard Qt folder dialog, when spawned from either QWidgets or QtQuick, will return an incorrect URL when used to navigate to a folder whose name ends with a trailing space.

For example, if you use it to navigate to a folder with the path `/home/username/folder ` (note the trailing space) it will return the URL `file:///home/username/`
