Comment 5 for bug 388975

I can confirm the same behaviour for me, on Lucid (64bit) with a Panasonic FZ-28 camera - but only in Pictbridge mode; when it is mounted as a storage device it just works like any other storage device.

My backtrace looks quite similar (although it's not that detailed since I can't seem to find a gvfs-dbgsym's that will install)
