Short answer: use repr. SAGE is just following

Thanks, setting a breakpoint at exit allowed me to get a stacktrace
which told me that
the function called before exit is xerbla_ in the dynamic library
liblapack.so.
So the LD_PRELOAD trick may work. I can't seem to get it to work with
sage yet though.
Is there a similar command to LD_PRELOAD

I think I agree with Joel here. str(...) should give something

It is unclear to me, from your response, if you understand the problem
with plot_vector_field in its current form. The example from the
wolfram site is somewhat misleading, since it uses a vector field of
the form (f(x),g(y)), but this
