gphotofs regressions

I have spent many a spare moment since Jaunty trying to understand why my Kodak digital camera import became broken. I am fairly confident it has to do with the switch to gphotofs. For what ever reason, it finds two devices of the same name and attempts to mount each causing a 'lock error' to be raised for the second attempt. I have chosen to blog about this regression after having my lp bug languish during Jaunty only to get worse in Karmic.

Now on Karmic, it is crap shoot whether the 'locked device' situation allows any functional import window to show. At least in Jaunty, I was able to just dismiss the error dialog and import the images from the first. I am currently using 'sneaker-net' to enable me to pull images with the SD card in the camera onto my Mini 9.

I have tried the gphotofs terminal tools and caught the following log with and without the external SD card installed:

The docs and searching has not produced much in answers. I would love to see this remedied for Lucid Lynx in April. It is things like this that will make it or break it for users of Ubuntu. Feel free to contact me if you have a solution.
