Volume 2: warning accessibility bus and segmentation fault on Travis

Oh lord. In an attempt to follow your advice I replied to this in the former post, thinking and believing I could just erase this one (since there isn’t that much new information here). But I can’t remove this post… So now the confusion is even larger (evil laughter). Right, feel free to ignore this post, and reply in the other one (i.e. here). Thanks and sorry for the mess.
