With .mp4 can add another that will cause this - video/x-m4v So for example if a user sets Videos as default thru "Default Applications" then these 3 are entered in mimeapps.list video/mp4= video/mp4v-es= video/x-m4v=
Nautilus only sets the first one so if the other 2 exist then the default for .mp4 cannot be altered thru nautilus until they are removed or edited to intended new default. Also if another player is set thru Default Applications & the above 3 are in mimeapps.list then the default for .mp4 will only be changed if that player has all 3 in it's .desktop's MimeType= line -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1280794 Title: Can't change default "Open with" application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1280794/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
