Isn't that exactly what I said above?

Anyway, on my ubuntu system, the old gthumb installs a desktop file 
(/usr/share/applications/gthumb-import.desktop) that runs this command 
when you choose "import with gthumb" in the popup:

sh -c 'gvfs-mount -u ~/.gvfs/gphoto2*; exec gthumb --import-photos'

So it does unmount all gphoto2 cameras before launching gthumb. That was 
introduced as a workaround to let gthumb import (with gphoto2) from 
cameras that are automounted by gvfs. Of course if you try this in 
combination with the new gthumb, it won't work because you don't want 
the unmount step.

If your camera is not mounted by gvfs automatically when you plug-in the 
camera, then that's a gvfs (or udev or whatever is responsible for this) 
bug. I'm not sure trying to workaround that in gthumb is the right way 
to fix this.

Maybe your camera is mounted automatically, but gets unmounted 
immediately again when you choose "import with gthumb" in the popup?
