[Ardour-Dev] Bleeding edge ardour crashes before splash screen

[Hans Baier]

Sorry, this time with debugging symbols included:

This crash occurs in bleeding edge Ardour3 when trying to create a new project
 (ubuntu gutsy studio i386 on Athlon64X2 / NForce4 with realtime kernel):
The weird thing is, when I start it with ./ardbg ardour-3.0
it works,
when I start it regularly, it crashes as below:
