"I don't understand why this is still an issue after 4 years." I make it closer to five years. Apparently freedesktop.org is not interested in updating their files.

But there are several Linux-based settop boxes that record videos in *.ts-files. So if application/x-linguist is obsolete then it should simply be replaced by video/mpeg. Otherwise the mime framework has to distinguish such files by inspecting their headers. If someone knows more about x-linguist files, please add a comment! The problem has already been reported upstream two month ago (see freedesktop.org above). But for 10.04 LTS we should fix it by a patch, if it is not fixed upstream by then. As a workaround copy the attached file to ~/.local/share/mime/packages/mpeg-ts.xml and update your mime-database with: $ update-mime-database ~/.local/share/mime To trigger the regeneration of failed thumbnails just delete them: $ rm ~/.thumbnails/fail/gnome-thumbnail-factory/*.png ProblemType: Bug Architecture: i386 Date: Sun Jan 3 17:47:29 2010 DistroRelease: Ubuntu 9.10 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release i386 (20091028.5) Package: shared-mime-info 0.70-0ubuntu1 ProcEnviron: PATH=(custom, user) LANG=de_CH.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-16.53-generic SourcePackage: shared-mime-info Uname: Linux 2.6.31-16-generic i686 To manage notifications about this bug go to: https://bugs.launchpad.net/shared-mime-info/+bug/502642/+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
