[Bug 981062] Re: gphoto fails to download image from camera

[Michael Terry]

Uploaded to precise-proposed (waiting to be approved).  I made two changes:
* Added the patch to debian/patches/series (otherwise it won't actually be applied)
* Removed the whitespace-only stanza from the patch, it was just noise.

Title:
  gphoto fails to download image from camera

Status in Rawstudio:
  New
Status in “gphoto2” package in Ubuntu:
  Invalid
Status in “libgphoto2” package in Ubuntu:
  Fix Released
Status in “gphoto2” source package in Precise:
  Invalid
Status in “libgphoto2” source package in Precise:
  Incomplete

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-image-and-download

  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:-
  http://sourceforge.net/tracker/index.php?func=detail&aid=3541332&group_id=8874&atid=108874

  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.
