The problem with using Toggled in the slot as I just tried it out is that it causes Dolphin to crash with a segfault. As Thomas Lubking explains it:
    
    The crash cause will have been the toggled signal which is prone to cause recursions when bound to slots which, well, toggle the action ;-)

I also made a small change to dolphinviewcontainer.cpp, that is I got DolphinViewContainer::setFilterBarVisible(bool visible) to emit the signal showFilterBarChanged. Then, I removed the updateViewActions() function from toggleFilterBar and setFilterBarFocus in the dolphinmainwindow.cpp file. Also, I guess we can re-introduce an updateFilterBar function to slim down usage of updateViewAction()?
