Nautilus and Gthumb, both of those use Gvfs to fetch photos/videos from cameras. (I wonder if there's some special handling in Gvfs that Shotwell could use here?)
Shotwell has a built-in logger that might help track this down. If you set the environment variable SHOTWELL_LOG=1 you may get some useful information. The easiest way to do this is to run the following from a command prompt: SHOTWELL_LOG=1 shotwell The log file is saved here: ~/.cache/shotwell/shotwell.log If you could replicate the problem while logging is enabled, post the log here and we'll take a look. Another thing to try is fetching previews from the GPhoto2 command line client. To install GPhoto2's command line client and download all the thumbnails off your camera into a "thumbs" folder, run these commands: sudo apt-get install gphoto2 mkdir thumbs cd thumbs gphoto2 -T Now the thumbs folder will contain essentially the same thumbnails Shotwell can see. (Note that these files are JPEGs, you may have to rename them to get them to open.) If you get a thumbnail for your video here but not in Shotwell, that means it's something we can fix entirely on our end. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to shotwell in Ubuntu. https://bugs.launchpad.net/bugs/1119260 Title: Shotwell should show video thumbnail before import To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shotwell/+bug/1119260/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
