Impossible to re-open a session

Installation & Configuration Linux
#1

Hi,
Impossible to re-open a session create in 10/2014 with ardour3 in ardour3, neither with ardour4.

It close with:

  • Ardour3:

So here is the backtrace in ardour4:

Is someone can help me to re-open it ?

Ubuntu 14.04 + lowlatency kernel + Kxstudio repos

I am also facing a similar issue - all my projects created a year back and which worked in ardour 4.1 don’t work anymore in ardour 4.2 or in ardour 3.
Logged a bug here with backtrace

error seems to be here

Just tried looking at the error message in my ardour 3.5.403 - looks similar to rcspam’s

Handled on IRC. In both cases the issue was with calf-plugins (calf-plugins-git from KXStudio). Uninstalling calf made the sessions load, in mendred’s case using calf (0.0.60) instead of calf-git also did the trick.

I reported the rakarrack lv2 issue upstream https://github.com/ssj71/rkrlv2/issues/8
