Impossible to open certain files with default org.gtk.Settings.FileChooser setting
org.gtk.Settings.FileChooser defaults to path-bar which is often unusable. Since it isn't usable with many files in a directory and deep directory structures are painfully slow it isn't a universal solution. Why not simply default to filename-entry so that users who need to access deep directories or files in directories of millions of files don't suffer? If someone is a special case and he knows they will never have a deep directory or a lot of files he can change it (but of course never would). Otherwise people are REQUIRED to have special secret knowledge of this setting and how to change it to access their files.
PS: If it were up to me I would just remove path-bar entirely since it is inferior in all known use-cases.
