What I find more a pain in the ass of the GtkFileChooser, it's that I can't type the path. It's very annoying, when you need to jump to a path that you have on the clipboard and you can't, and you are forced to navigate to these path because the removed a simple text field to puth the path.
The equivalent from QT/KDE does this far better. It allows the user to switch from the graphical "user friendly" path representation to a crude text field where you can write/removed/modify/copy/paste the path.
CTRL+L works and I have been using it but I had to google it first to learn about it!
It is not intuitive and bad experiemce. There could be a toolbar button for that or a permanently-visible address box or it could read clipboard and suggest something, be smarter.
