Please describe the problem:
Try to navigate to /usr/bin using a no-frills GtkFileChooserDialog. My computer is a bit old, but it's far from being obsolete and it sometimes takes minutes (!!) to display that directory.

I implemented a very similar file list using a GtkTreeView in my own application and reading the directory, even that large, takes very little time (~2 seconds for /usr/bin). I had to make sure the view is disconnected from the model before doing the update, but it looks like GtkFileChooserDialog is doing something else - because there's a lot of hard-drive activity, not just CPU.

Will you please fix it? I need to navigate to /usr/bin once in a while to select what app to open files with from Firefox, and the experience ranges from annoying to `kill firefox-bin` because I don't have the time to wait for the file chooser to say hello to every file.

I have GTK 2.10. Please let me know if there's something I can do to help.

Thanks!
