For raw file previews, the Preview thumbnail generator used by the Dash doesn't handle all types of raw files, so the lens is using the "*_shotwell.jpg" file Shotwell generates in the same folder as the raw file. A file it generates only when the raw is double clicked in Shotwell.
One way to fix it would be to use the largest available thumbnail (thumbs360/) in the Preview when the file is not supported, which is obviously quite hard to check, and could also introduce the need to maintain a hardcoded list of raw file extensions. Ideally, we could ask the Dash devs for a Unity method to check if an extension is supported in the Dash (results and previews). I will file a Unity bug for this and raise the subject next week at UDS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069225 Title: Shotwell thumbnails not shown for raw photos in results To manage notifications about this bug go to: https://bugs.launchpad.net/unity-lens-photos/+bug/1069225/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
