JPG metadata extraction / Photoshop

Dear all,

when adding a JPG modified within Photoshop Elements I get:

2014-06-01 16:22:43,356 DEBUG [LibraryAdditionsCheckerThread] Found file 'IMG_0582-test.JPG', checking if it's already in the Library

and the JPG isn't added to the library

[root@barney log]# java -version
java version "1.7.0_55"
OpenJDK Runtime Environment (rhel-2.4.7.1.el6_5-x86_64 u55-b13)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

Any clue what could be wrong? The JPG displays correctly with any viewer ...

The library Serviio uses doesn't like the file for some reason. it might be something they already know about and will fix in the future.
