Thanks to both of you for investigating it!
I pushed a patch with a workaround as Nicolas suggested. Now the
quiver stuff works properly again...

I reduced the segfault to:
sage: M = matrix(ZZ,3,[0,1,0,-1,0,-1,0,1,0]); M

Hi,
I just compiled 4.8 and the combinat queue. Now, I get a segfault when
building a quiver:
sage: Q = Quiver(['A',3])
...
