Last version of Ardour 3 can't run in my ubuntustudio 12.04

Dear friends!.

I checked the last version of Ardour 3 (3.5.14) amd64 into my ubuntustudio 12.04 amd64 and it can’t load any project.
The error message was:

(ardour-3.5:3957): GLib-GObject-WARNING **: Attempt to add property gtkmm__CustomObject_N9Gtkmm2ext23CellRendererPixbufMultiE::active after class was initialised

Failed to register port “MTC”, reason is unknown from here
GLib (gthread-posix.c): Unexpected error from C library during ‘pthread_mutex_lock’: Argumento inválido. Aborting.

Could you please explain me what happen?.



If you created the projects in an earlier version of Ardour, it is likely you are running into an issue with translations that was recently fixed, where the translated port names ended up being duplicates of each other.


This has been fixed in git, and a new “hotfix” release will be out (probably next week) to make it more readily available. In the meantime, you could make it work by running Ardour in non-translated mode from the command line: LANGUAGE=en /opt/Ardour-<VERSION>/bin/ardour3 (substituting the appropriate text for <VERSION>).
