Attempting to add metadata to unsupported types

http://dev.exiv2.org/wiki/exiv2/Supported_image_formats
http://docs.python.org/library/imghdr.html
im.format

Also Phatch should first check if there are eg Exif[.]Canon tags, otherwise it doesn't make sense.

Strangely enough exiv2 states it supports png, but I removed it from the list. This bug was a huge amount of work to fix it. And I am not quite sure if it will work well. Please test.

Please test if this is fixed.

Unfortunately I'm still getting the exception:

This bug was fixed in the package phatch - 0.2.1-4

---------------
phatch (0.2.1-4) unstable; urgency=low

  * Add mlocate as an alternative dependency to locate (Closes: #548251)

phatch (0.2.1-3) unstable; urgency=low

  * replace --install-scripts=/usr/bin with --prefix=/usr
    (so that data files will be installed in the right place as well)

phatch (0.2.1-2) unstable; urgency=low

  * pass --install-scripts=/usr/bin to setup.py (otherwise it will FTBFS when
    default Python version is >= 2.6)

phatch (0.2.1-1) unstable; urgency=low

  * debian/copyright:
    - Added copyrights for the new contributions.
  * debian/control:
    - Added python-notify and libtiff-tools as dependencies

  [ Emilio Pozuelo Monfort ]
  * debian/rules:
    - Install phatch in /usr/share/phatch instead of as a public module.
    - Stop removing a file from a pysupport folder. With the above change
      is not necessary anymore. Closes: #516322.
  * debian/copyright:
    - Add "Copyright" to the debian copyright.
    - Update years.
  * debian/control:
    - move python-nautilus and pkg-config to Build-Depends-Indep.
    - Wrap depends.
  * Update my email address.

  [ Piotr Ożarowski ]
  * Splitting out the package, new binary packages:
    - phatch-cli (command line interface)
    - phatch-doc (documentation for developers)
    - phatch-nautilus (Python nautilus integration)
  * Add blender and inkscape to phatch's Suggests
  * Add imagemagick, libjpeg-progs, exiftran, xcftools and dcraw to
    phatch-cli's Recommends (new actions will use them)
  * Add ttf-freefont and ttf-thai-tlwg to phatch-cli Depends (and add symlinks
    to use fonts from these packages instead of local copies)
  * Add locate to phatch-cli's Depends (used to find fonts)
  * Add python-sphinx and locate to build depens (docs are regenerated at
    build time)
  * Add lintian override for extra-license-file in phatch-doc (false positive)
  * Bump Standards-Version to 3.8.3 (no changes needed)
