Segmentation fault (core dumped) - Session corrupted? Hours of work lost.

I was working happily in Ardour 2.0.4. I had a bunch of tracks recorded, I was laying down a bass line and - blammo Ardour shutdown. Now when I try to open this session Ardour briefly opens and then shuts down. I can open other sessions, but not this one.

Here’s the output from the terminal:

Again, I can open other sessions, just not this one. Unfortunately I have a lot of time invested in this session and the fact that it’s become mysteriously unusable has me grinding my teeth a little bit.

I upgraded to Ardour 2.0.5 and that didn’t help.

Any help would be greatly appreciated.
I’d be happy to upload any files if needed. Just tell me where to put them or where to email them. I can also setup an FTP server if I have to.

Thanks!
