Comment(by jpflori):

 By the way, that does not happen when you do not use the hold parameter
 followed by the simplify call :

 {{{
 sage: I.log()
 1/2*I*pi
 sage: var('I')
 I
 sage: I.log()
 log(I)
 sage: restore('I')
 sage: I.log()
 1/2*I*pi

 }}}
 So 'I' gets restored but maybe Maxima gets the var('I') which was created
 and not the default numeric 'I'.

 Here is another strange thing:

 {{{
 sage: I.log()
 1/2*I*pi
 sage: J = deepcopy(I)
 sage: bool(I == J)
 True
 sage: J.log()
 1.57079632679490*I
 }}}
