Summary0001820: segfault every time on creating a new session
Descriptionhi,
this bug i about ardour2-ongoing.
i just realized that if i start ardour and try to create a new session, ardour will segfault every time, after that, the session is created and i am able to open it via session dialog.
to reproduce:

-start ardour
-in the session dialog choose 'new session'
-choose the session path
-click 'new'
-ardour segfaults creating a coredump
....
-starting ardour again
-now choosing 'open session'
-choose the session which before should get created
-ardour successfully opens the session.


here is the backtrace:
