Image rotation results in broken EXIF Orientation and Resolution tags

[Eugene Crosser]

Binary package hint: gthumb

When gThumb physically rotates images (including auto-rotation on camera
import), the resulting image has broken EXIF tags for Orientation and
[XY]Resolution:

$ jhead -v 2010_11_07-14_24_33.jpg
Exif header 4282 bytes long
Exif section in Intel order
(dir has 16 entries)
    Make = "Canon"
    Model = "Canon DIGITAL IXUS 80 IS"
    Orientation = 0
    Orientation = 1
    Orientation = 1

Nonfatal Error : '2010_11_07-14_24_33.jpg' More than two orientation in Exif
    Orientation = 1

Nonfatal Error : '2010_11_07-14_24_33.jpg' More than two orientation in Exif
    XResolution = 0/327962
    XResolution = 180/1
    XResolution = 180/1
    XResolution = 180/1
    YResolution = 180/1
    ResolutionUnit = 2
    Software = "gthumb 2.11.3"
    DateTime = "2010:11:07 14:24:33"
  [...]

This (apparently) results in Shotwell segfaulting on import of such images, and
perl Image::Info complaining about invalid RATIONAL value for XResolution.

System is Ubuntu Maverick on AMD64.

Upgrading exiv2 to 0.20 *and* gthumb to 2.12 solves the problem
(upgrading any single one of these packages does not!)

For the record:
exiv2:
  Installed: 0.20-2
gthumb:
  Installed: 3:2.12.0-1~webupd8~maverick

to package maintainers: please consider pushing the updates.
