ssh bookmarks not showing any contents

Using Marlin 0.1-0~874~precise1
In Nautilus I have a number of ssh connections within my local network set as bookmarks. Authentication is by keys.

In Marlin I can see the bookmarks in the places pane. If I click on the bookmark then it connects to the server ok but no files are shown (it does not say it is empty, it merely shows no files). For example I see in the address bar
owl.local > media > usbhdd
which is correct, but no contents are shown. Strangely if I navigate up by clicking on 'media' then it correctly shows the contents of that folder and from there I can navigate up and down and all contents appear correct, except if I return to the original folder (usbhdd in this case) in which case it still shows empty.
This appears to be the case for all such bookmarks. Reloading the view does not help.

If I connect using Connect to Server then the contents are shown correctly. In that case the address bar shows <user>@owl.local/media/usbhdd. It does not show the user in the failing case, though it must have used the user name to connect.

I tried to run Marlin with debug logging by running, from a terminal, marlin -d but no debug output appeared and I could not find a log file.
