Bug#532162: gphoto backend is not working with Ricoh Caplio R5

[Giuseppe Sacco]

Package: gvfs-backends
Version: 1.2.3-1
Severity: important

When I plug my camera nothing happens. This is my configuration:

1. on the "media" panel of file management preference, I set "open
folder" on the camera setting;

2. the gphoto monitor is active:
giuseppe at scarafaggio:~$ ps axu| grep gphot
giuseppe  6215  0.0  0.1   9560  4040 ?        S    09:11   0:00 /usr/lib/gvfs/gvfs-gphoto2-volume-monitor

3. hal recognized the camera, as shown with lshal:

udi = '/org/freedesktop/Hal/devices/usb_device_5ca_221a_noserial_if0'
  access_control.file = '/dev/bus/usb/001/008'  (string)

  usb.vendor = 'Ricoh Co., Ltd'  (string)
  usb.vendor_id = 1482  (0x5ca)  (int)
  usb.version = 2.0 (2) (double)

4. I have read/write permission the usb device:

giuseppe at scarafaggio:/etc/hal/fdi$ getfacl /dev/bus/usb/001/008
getfacl: Removing leading '/' from absolute path names
# file: dev/bus/usb/001/008
# owner: root
# group: plugdev
user::rw-
user:giuseppe:rw-
group::rw-
mask::rw-
other::r--

5. my user is prenset in group plugdev
giuseppe at scarafaggio:~$ id -a
uid=2000(giuseppe) gid=1000(giuseppe) gruppi=20(dialout),24(cdrom),25(floppy), \
 29(audio),30(dip),44(video),46(plugdev),104(powerdev),106(netdev),110(scanner), \
 112(fuse),1000(giuseppe)

6. camera is detected by kernel and no other messages are logged in
syslog:

giuseppe at scarafaggio:/etc/hal/fdi$ sudo tail -25 /var/log/syslog | egrep -v dhclient\|CRON\|wpa_suppl

Jun  7 09:38:57 scarafaggio kernel: [ 1745.733741] usb 1-6: configuration #1 chosen from 2 choices

7. mounting the camera via "gphotofs /tmp/mountpoint" initially works,
but stop after copying a few images (this is a different problem, I
think)

8. importing photo via gthumb initially works: all previews are show
correctly, but after pressing the "import" button, nothing happens
(again, this is a different problem, I think).

Bye,
Giuseppe
