Chris, thanks for the quick and useful reply! I've updated Totem's desktop file per your suggestion and it fixed the problem for me locally. Documenting the workaround for anyone who would stumble upon this issue:
- edit /usr/applications/totem.desktop (requires sudo) by adding "x-scheme-handler/mms" at the end of "MimeType" line - run `sudo update-desktop-database` to update the MIME types cache -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/751101 Title: mms: links don't open in totem -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
