It appears the file saved by UDM under
~/.cache/com.ubuntu.gallery/HubIncoming/ has the expected checksum, but
when copied over to ~/Pictures, its checksum changes. A wild guess is
that gallery-app modifies the file (maybe the exif metadata).

Note that when saving the same image three times in a row (and renaming
the file in between each download), I’m getting three different
checksums, which suggests that the contents of the file change in a
different way (maybe the exif timestamp?).

** Package changed: webbrowser-app (Ubuntu) => gallery-app (Ubuntu)

** Changed in: gallery-app (Ubuntu)

Title:
  Incorrect file digest when it is downloaded through webbrowser-app
  with touch

Status in gallery-app package in Ubuntu:
  New

Bug description:
  I download an image from a webpage and the sha1 digest is not the same
  than the original. It is happening at least in the krilling (touch).

  I tested this scenario with different images and always it is
  happening the same.

  Steps to reproduce:
  1. Go to http://lillypilly.canonical.com/~platform-qa/page3.html
  2. Touch in the ubuntu image
  3. Select Save image
  4. Select to open with the Galery
  5. Once it is downloaded, press open
  6. The file is in ~/Pictures/ubuntu.jpg

  The file sha1 digest is 7cad64e34de2eebe73b49756b09a50a4a1948c7a
  The original sha1 digest is 429cbd692c4abd3e5c785edf5dcf0993d21076b1

  If you download the image either with chrome or firefox, the obtained
  digest is the correct one.
