3-channel bus crash and unable to open

Installation & Configuration Linux
#1

Hello,
I cannot seem to add a 3-channel bus. Every time I try, it crashes Ardour and then the session cannot be opened again.

Steps to reproduce:

  • Start new session
  • Add new bus with 3 channels

(ardour-3.5.403:3452): GLib-GObject-WARNING *: Attempt to add property gtkmm__CustomObject_N9Gtkmm2ext23CellRendererPixbufMultiE::active after class was initialised
drop flushed event on the floor, time 0 to early for 1 + 0

Aborted

$ ./ardour3 --version bnd txt domain [gtk2_ardour3] to /opt/Ardour-3.5.403-dbg/share/locale Ardour3.5.403 (built using 3.5-403-gec2cb31 and GCC version 4.4.6)

This crash has nothing to do with the bus. The bug has almost certainly been fixed already in the development version, which has recently entered the pre-release phase and can be tested via the nightlies website, http://nightly.ardour.org/

Paul,
You are correct, I tried version Ardour_64bit-3.5.4177-dbg and it behaves as expected.

Thank you.
