[ardour-dev] backtrace of a crash (very recent CVS)

[Christophe Combelles]

Hello !

This is a crash with ardour CVS 20050701
(0.598.1 with libardour 0.894.1).
Built with DEBIAN=no
I just launch ardour, then open a recent session -> segfault.
(The session was created with 0.9beta28)
I'm running Sarge with the default jack provided with this distro.
