ardour 3 alpha 4 crashed on start

Hello everyone.
when I try to use the alpha 4 of ardor crassha I start, I do all the steps to create a new project or re-open a saved ardor but then closes and I can not work, it’s a bug?
I’m on 11.04

Well, were not supposed to discuss Ardour3 on this forum (yet), but I have the same problem with recent versions (2 versions in past week), so maybe there is a major bug in the recent SVN versions. Opps, now I see you are talking about akpha4. You might want to check this post:
