[ardour-users] Ardour2-svn 912 Segfault on Dapper

[Nicola Mattei]

Hi to te list. I currently have problems with most recent svn versions
of ardour2.
It builds fine but, when I execute it, it segfaulted every time I try
to add a normal track (every kind of them, from "mono" to "manual
setup" after displaying a message box that says:
"programming error: unknown track mode in add route combo = Normal"
Here's the command line output:

Anyone else experienced such a problem or maybe it's due to something
wrong in my building environment?
Is this a known bug or I have to submit it to mantis?
I'm running an ubuntu dapper and the crash reported is from svn revision 912.

Many thanks,
Nicola
