Bug Description
libgphoto2-2 should be upgraded to the latest version - 2.4.14
[Impact]
Users of Canon EOS (Rebel) series cameras cannot download images remotely from their cameras to their computers.
[Test Case]
The command:-
gphoto --capture-
causes the camera takes a photo, but then gphoto hangs. If I use Ctl-C to stop gphoto, I get:-
ERROR: Could not get image.
ERROR: Buggy libcanon.so?
The result should be that gphoto downloads the image to the PC and deletes it on the camera.
This works again if libgphoto2 is upgraded to version 2.4.14, which is available in Quantal.
[Regression Potential]
The potential for regression will be limited by the fact that it only affects libgphoto users. Worst case is that other cameras may stop working if a new, unkown bug is lurking in the library.
Bug was raised (and closed) on Sourceforge for the gphoto2 package and is visible at:-

Apparently, this bug was inserted into 2.4.13 which has since been fixed in 2.4.14
The latest (pre 2.4.13) version I used was 2.4.11 in Oneric, which also works.
TEST CASE
1. Confimed that libgphoto2 version 2.4.13-1ubuntu1 was installed on my machine.
2. Ran the command: gphoto --capture-
3. Image failed to download
4. Set up apt to use precise-proposed
5. Upgraded libgphoto2 to version 2.4.13-1ubuntu1.1
6. Ran the command: gphoto --capture-
VERIFICATION DONE
1. Image successfully downloaded.

I downloaded libgphoto2- 2_2.4.11- 3_i386. deb for Ubuntu 11.10 and installed it. Now the camera takes photos and downloads them to the camera.
I then used:
sudo apt-get dist-upgrade
to restore the original version to libgphoto2- 2_2.4.13- 1ubuntu1_ i386.deb and the bug returns.
