log is a multivalued function. Most CASes will return log(x) and not log(abs(x)) as the antiderivative of 1/x. So that is probably the situation here - it is true in the multivalued sense?

Edit: here's how to set that maxima variable - but you have to do it in the "calculus" copy of Maxima inside Sage.
sage: integral(1/x,x)
log(x)
sage: maxima.eval(" logabs:true")
'true'
sage: integral(1/x,x)
log(x)
sage: maxima_calculus.eval(" logabs:true")
'true'
sage: integral(1/x,x)
log(abs(x))
