92096e1aa7 Tiff: Bail out if there are no valid exif tags 
Some corrupted images end up with no valid exif tags.  This case is
currently not handled gracefully, resulting in the following:

    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/Users/mitchhumpherys/Sites/str-prod/env/lib/python2.7/site-packages/PIL/JpegImagePlugin.py", line 391, in _getexif
        return _getexif(self)
      File "/Users/mitchhumpherys/Sites/str-prod/env/lib/python2.7/site-packages/PIL/JpegImagePlugin.py", line 426, in _getexif
        exif = dict(_fixup_dict(info))
      File "/Users/mitchhumpherys/Sites/str-prod/env/lib/python2.7/site-packages/PIL/JpegImagePlugin.py", line 407, in _fixup_dict
        return dict([(k, _fixup(v)) for k, v in src_dict.items()])
      File "/Users/mitchhumpherys/Sites/str-prod/env/bin/../lib/python2.7/_abcoll.py", line 414, in items
        return [(key, self[key]) for key in self]
      File "/Users/mitchhumpherys/Sites/str-prod/env/lib/python2.7/site-packages/PIL/TiffImagePlugin.py", line 854, in __getitem__
        self._setitem(tag, handler(self, data, legacy), legacy)
      File "/Users/mitchhumpherys/Sites/str-prod/env/lib/python2.7/site-packages/PIL/TiffImagePlugin.py", line 534, in _setitem
        dest[tag], = values
    ValueError: need more than 0 values to unpack

Just bail out if there aren't any valid tags.

Fixes #1722

72c45e6f5d Fix Fatal Python error: UNREF invalid object in debug builds 
PyObject_Del() should only be called on the self object in
a dealloc call, not after failing to make a new object.
Replace with Py_DECREF, which eventually calls PyObject_Del()
