Comment 5 for bug 1592177

I'd say the solution is to remove the restore_filechooser_typeaheadfind.patch, see this commit:

https://git.launchpad.net/ubuntu/+source/gtk+3.0/commit/?id=99cb6330706eadb58bf9d3c5b77120fdd5971189

After all, such patches were removed from Nautilus for a good reason. It should also be removed from the file chooser, since currently it breaks both behaviors. Both search and type ahead are currently broken, by removing this, at least search will work, which is the upstream behavior.
