I get "Cannot open corresponding directory" when I click the "Home" icon while using "Syncronized browsing".
I think this is because some of the directories on my remote host (Linux) are logical links. Consequently, the relative path of the home directory from the directory I'm in is different on the two systems. I'm not sure, but I think the problem is less likely if I click the "home" icon on the remote site.
One workaround would be to handle the "Home" icons differently when Syncronised browsing is active. When clicked, you temporarily ignore the "Syncronised browsing" selection, and emulate the action of the user clicking both home buttons.
