Description of problem:
Canon ixus cameras have two transfert protocols, PTP and "another one than USB mass storage". gphoto2 implements them both but only PTP works. The second one is know to be broken 
Gphoto2 tries to autodetect camera by alphabetic order. And as you can see from the output of "gphoto2 --list-camera"
"Canon Digital IXUS 700 (normal mode)" (EXPERIMENTAL)
"Canon Digital IXUS 700 (PTP mode)"
the broken protocol comes before the working one, so the autodetect feature can't be used (read gthumb does not work).
 http://sourceforge.net/mailarchive/forum.php?thread_id=7953860&forum_id=32960 for the most recent message.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug the camera
2. gphoto2 --list-file
3. read the error message about lock key
Actual Results: In short photos cannot be retrieved. You get an error message like this one:
*** Erreur (-114: 'OS error in camera communication') ***
A trivial patch is to remove the broken protocol from libgphoto2, the camera will be detected as a normal PTP camera and will be supported.
Canon IXUS 700 is also known as PowerShot SD500 or IXY Digital 60

Patch against libgphoto
I have rebuild the RPM with this patch applied and all is working fine !
Can you please retest your issue with gphoto2-2.1.99 from rawhide?
I believe this is fixed in rawhide.
Sorry for the delay but I missed your previous comment.
I just tested gphoto2 on a FC2t5 and it seems the bug hasn't been fixed
# rpm -qa | grep gphoto2
# env LANG=C gphoto2 --auto-detect
Canon Digital IXUS 700 (normal mode) usb:
# env LANG=C gphoto2 -P
Detected a 'Canon:PowerShot SD500 (normal mode)'.
*** Error ***
lock keys failed.
*** Error (-114: 'OS error in camera communication') ***
# env LANG=C gphoto2 --camera "USB PTP Class Camera" --port "usb:" -P
Downloading 'IMG_3941.JPG' from folder '/store_00010001/DCIM/639CANON'...
Saving file as IMG_3941.JPG
Normal mode is still the default mode and still does not work, so you will be
unable to import photos using gthumb.
I can attach a full debug log if needed.
I am having the problem with my Canon IXUS 700. I tried both gphoto2-2.1.99-8
and gphoto2-2.1.99-10 to no avail. I'll attached debug output generated with:
env LANG=C gphoto2 --debug --summary
I'll gladly test new gphoto2 RPMs if needed.

debug output with canon ixus 700 and gphoto2-2.1.99-10
More information! Ixus 700 must use PTP mode. I got this info from gphoto2 list.
But, as said, even the latest RPM does not work yet at the moment.
you need to remove all 3 occurences of the USB id pair, not just 1. (the line
above and below)
So what's the status with this? All information needed should be available to
roll out a package containing needed fixes. Thanks.
Still does not work out of box.
For IXUS 700 patch #1 is needed. I'm running this patch since one year...
Others IXUS probably need the same kind of patch but I only own an IXUS 700 so I
can't tell if it is needed or working...
I can test new package if needed.
Ok, I've remmoved Ixus 700 in gphoto2-2.1.99-13. Can you please retest this
Probably stupid question but Where can I find gphoto2-2.1.99-13 ?
In /pub/fedora/linux/core/development/i386/os/Fedora/RPMS on
download.fedora.redhat.com only -12 is available not -13.
Just give it some time to synchronise. It went through build system and will
appear there really soon.
I am happy to confirm that with gphoto2-2.1.99-13 my Canon IXUS 700 works now
