Comment:

 The following now displays correctly using Sage Version 4.3.1 (Release
 Date: 2010-01-20)
 with pynac 0.1.11 (and also without any patches mentioned in this ticket)

 {{{
 sage: f=(1/2-1/2*I )*sqrt(2)

 sage: f
 (-1/2*I + 1/2)*sqrt(2)

 sage: f-1/2*sqrt(2)
 -1/2*I*sqrt(2)

 sage: f+1/2*sqrt(2)
 (-1/2*I + 1)*sqrt(2)

 sage: f-I*1/2*sqrt(2)
 (-I + 1/2)*sqrt(2)

 sage: f-I/2*sqrt(2)
 (-I + 1/2)*sqrt(2)

 sage: f+I/2*sqrt(2)
 1/2*sqrt(2)

 sage: latex(f)
 \left(-\frac{1}{2} I + \frac{1}{2}\right) \, \sqrt{2}

 sage: latex(f+I/2*sqrt(2))
 \frac{1}{2} \, \sqrt{2}

 sage: (1-I)^2
 -2*I

 sage: (1+I)^2
 2*I

 sage: (1+I*sqrt(2))^2
 (I*sqrt(2) + 1)^2

 sage: expand((1+I*sqrt(2))^2)
 2*I*sqrt(2) - 1
 }}}
