 We want to fix the following error on sage 5.4. Given the input

 {{{
 sage: p = disk((0,0), 5, (0, pi/4), color='red')
 sage: p += disk((0,0), 5, (pi/4, pi/2), color='red', alpha=0.5)
 sage: p.save("test.pdf")

 }}}
 we get the error

 {{{
 TypeError: Don't know a PDF representation for <type
 'sage.rings.real_mpfr.RealLiteral'> objects.

 }}}
 This can be fixed in the backend quite easily.
