Comment 67 for bug 133133

I have two systems with Mozilla/5.0 (X11; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0 SeaMonkey/2.16 installed. One of them is running on KDE 4.6.0 on openSUSE 11.4, and the other KDE 4.9.5 on openSUSE 12.2. On the first one, "Open containing folder" correctly opens the directory using the default KDE file manager, Dolphin. On the second one, the correct directory is opened using the default Gnome file manager, Nautilus. No idea why one system correctly uses Dolphin but the other incorrectly chooses Nautilus.
