Public bug reported:

libthumbnailer0 1.0+14.04.20140307-0ubuntu1
Nexus 4, latest build from proposed with gallery-app from this PPA:
https://launchpad.net/~ci-train-ppa-service/+archive/landing-015/

The thumbnailer crashes when trying to get orientation data from a
picture (attached) taken by the camera on the Nexus 4. The crash file is
attached too and happens on the desktop as well as device.

Here is stack trace. 
[Thread debugging using libthread_db enabled]

such file or directory.

Seems that 
 ExifEntry *e = exif_data_get_entry(ed, EXIF_TAG_ORIENTATION);
returns null and that is being used later.
