Comment(by nthiery):
Yes, it now applies smoothly on 4.5.2, and compiles. Thanks!

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).

Same problem with the example taken from the documentation:

Should I be using 4.5.3 (being downloaded)?
