libgphoto2 causes F-Spot import failure

Sorry about the short description in my first post!
When I try to import from my camera using F-Spot I get an error about not being able to lock the device. I unmount the camera and try again and I get an "error writing to port". Here's the terminal output:

~$ f-spot

Please install the "gphoto2" package, make sure that your camera gets unmounted after plugging it in (press the "umount" button in the dialog which pops up), and do

  gphoto2 --debug --debug-logfile /tmp/gphoto.debug.txt -L

Does this print an error message, or a list of files on the camera? Please attach /tmp/gphoto.debug.txt if it prints an error and fails. Thank you!

gphoto2 is already installed as are libghoto2-2, libghoto2-2-port. I got the error:

~$ gphoto2 --debug --debug-logfile /tmp/gphoto.debug.txt -L
*** Error (-35: 'Error writing to the port') ***

Attached is the debug file.

Additionally in GThumb viewer I get an error that camera contains no images when in fact it does.

The trace has:

0.561725 gphoto2-port-usb(1): USB device (vendor 0x4b0, product 0x108) is a mass storage device, and might not function with gphoto2. Reference: http://www.linux-usb.org/USB-guide/x498.html

I think that it was mounted as disk already makes it not accessible to sierra mode.

Please just use it as mass storage device.

It used to work great in Sierra mode. I'll miss being able to import..

for it to work in Sierra mode it must be able to detach the usb storage driver (the sierra mode is hidden in the sstorage mode).

libgphoto2 is no longer detaching mass strorage cameras anymore (since it caused too much problems), you can do this yourself manually if necessary.

I have unmounted and tried importing as from a mass storage device-doesn't work either. Is there another way? Am I missing something?

Since this report have a long time without activity, could you check (if is possible) in latest version included in Karmic if this issue is still happening? Thanks in advance.

Sorry to have not responded sooner. I'm no longer using the camera or the laptop. I upgraded the TiBook to Karmic and it became completely non-functional.

I believe this could be related to bug #74279 that I have been complaining about for some time. I tried the above commands with my Nikon D300s with just the CF card installed (causes F-spot to fail) and the first time I ran the command I got this:
=================================================================
gphoto2 --debug --debug-logfile /tmp/gphoto.debug1.txt -L

*** Error ***
PTP General Error

*** Error ***
An error occurred in the io-library ('Unspecified error'): No error description available
*** Error (-1: 'Unspecified error') ***

For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list <email address hidden>, please run
gphoto2 as follows:

    env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --debug --debug-logfile /tmp/gphoto.debug1.txt -L

Please make sure there is sufficient quoting around the arguments.

=================================================================
Second time I ran the command it worked as far as I could tell:
=================================================================

gphoto2 --debug --debug-logfile /tmp/gphoto.debug2.txt -L
