Now that I try, via File->OpenFolder in Gnome-mplayer, the mp4 file is greyed out and not possible to select. But it can be played via File->OpenRecent

I have not tweaked the system or installed some extra package, only installed Lubuntu into a non-English language (Swedish). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286660 Title: gnome-mplayer crashes when trying to play video file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-mplayer/+bug/1286660/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
