Comment(by jason):
No, it's deeper than that. __rmul__ should call the right coercion stuff
so that _rmul_ is eventually called. So far, I've traced it down to this:
{{{
sage: p=x.parent()
sage: p.get_action(3.parent(), operator.mul,False)
------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component
of Sage has a bug in it (typically accessing invalid memory)
or 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 (sorry).
