Hi Paul and the list,

I have built the last release and if i want to create a "Send' route to a 
Stereo Bus, Ardour will be fine with one channel only.

But if the Bus is stereo and i want that my "Send' route has 2 channels, then 
adding one make ardour freeze (segfault).

And as a final note, this bug explain why i couldn't load my project made with 
Ardour 0.9beta.11.. If i remove manually the Send xml section in the project, 
it will load fine.  My Send routes are generally stereo.

I hope it is reproducible at yours, here is another gdb output..
Debian Sarge
Ardour 0.9b17.1
