New issue 2171 by asmeurer: oo "eats" Integral
http://code.google.com/p/sympy/issues/detail?id=2171

I haven't looked into why it does this yet, but for whatever reason oo eats Integral(oo, x):

In [245]: Integral(oo, x)
Out[245]: ∞

Integral should always remain unevaluated by default. This is actually a wrong result anyway, and it propagates to regular integrate():

In [241]: integrate(oo, x)
Out[241]: ∞

The answer should be oo*x.
