Steps to reproduce

1. Open PCManFM
2. Open a folder different to the current one
3. Switch to "Detailed List View" (Ctrl+4 or [top bar]->View->Folder View Mode->Detailed List View)
4. Try to use mouse buttons 4 and 5 to go between previous and next folders in history (doesn't work)
5. Switch to any other view
6. Repeat step 4 (works)

GTK 2 or 3? If GTK 3, did it work with GTK 2?
