Public bug reported:
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.
