Summary0008660: Ardour crashes when editing automation
DescriptionUsing Ardour 6.6.216 (nightly), Ardour has been crashing when trying to edit automation (pitch bend for Vitalium) in my current project.

As suggested by Paul, I tried disabling DrumGizmo, but it still happened. The log 'gdb.txt' is with DrumGizmo, while 'gdb2.txt' is without.
Steps To ReproduceOpen the session, try to add automation points (in this current session).
TagsNo tags attached.
