Comment(by jdemeyer):
I still want to investigate some more, for example I have not checked that
it is really this ticket which causes the problems (but you do see
"linbox" appearing in the backtrace).
Strangely, even building the documentation crashes:

------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component of Sage has a bug
in it and is not properly wrapped with sig_on(), sig_off(). You might
want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.
