Is this a known issue? Using sage 8.3 beta 6.

I reported this at

sage: var('t')
sage: integrate(exp(t)/(t + 1)^2,t,algorithm="giac")

But using giac directly, it can integrate it with no problem

// Using locale /usr/share/locale/
// en_US.utf8
// /usr/share/locale/
// giac
// UTF-8
// Maximum number of parallel threads 8

So why did sage return udef for this result?
