After removing custom thumbnailers, copying a jp2 file using ctrl-C ctrl-V causes nautilus to crash about one time. gnome-thumbnailer tries to create a thumbnail, but it can take several seconds, and if nautilus is reopened and navigated to that folder again, it will crash again. However, after this has been completed, nautilus won't crash. (In fact, top reveals that it's eog that creates the new thumbnail if you use ctrl-C ctrl-V in nautilus.)
If the new file name is obtained a different way, like using 'mv' on the command line, navigating to that folder in nautilus will cause a crash without attempting to generate a new thumbnail. So even if you wait several seconds, no thumbnail will exist for the file and nautilus will crash every time you navigate to that folder until you delete the file or rename it to a path for which it will have a valid thumbnail (meaning the file's mtime is correct). So this might only affect jpeg-2000 files, and not all files for which there is no valid output. Maybe with other files, the default thumbnail options (the ones not recorded in /usr/share/thumbnailers) consistently create at least a failed thumbnail, while this doesn't happen with jpeg-2000 files. But since nautilus is crashing before eog finishes creating a thumbnail (if using ctrl-C ctrl-V to copy), nautilus might be relying on a separate process from what it depends on for, say, obtaining a 'failed thumbnail' result for incomplete mp4 files, which don't cause a crash. One difference is that while gnome-thumbnailer has code for handling image formats as a fallback method, it isn't for video formats. I'm not sure if it's nautilus or gnome that's calling eog to create a thumbnail when ctrl-C ctrl-V is used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1444790 Title: crash if thumbnailer fails to produce output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1444790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
