Hi, have you managed to get this same crash again at all? It seems like a memory error and the trace is not useful :/ Marking as incomplete pending some feedback, thanks.

I was doing nothing, it happens just as I was running the new beta2 live CD

So, can you reproduce it?
If yes, what particular steps should we take to recreate this bug?
