There is a workaround for me and that is to import the photos again in shotwell. There is an option to get rid of all capitals in the filenames. Seems to me that some developer at Shotwell had a comparable problem and made a solution for it.

When I change the extension to jpg (no capitals) the very same files are recognized as images. The dialog box shows 'images' and I can't select the 'all files' option - this could perhaps also solve the problem. I have found a really old bug description that seems to report the exact same problem. https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/221409 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1095321/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
