I am trying to run the following integral in version 9.0, but it fails:

Integrate[
 2 I (-1 + 
  x) ((-8 + 12 x - 6 m\[Pi]^2 x - 2 m\[Pi]^2 x^2 - 
   4 x^3)/((1 - x)^2 + 
   m\[Pi]^2 x) + ((4 - 2 x + 4 m\[Pi]^2 x - 8 x^2 + 
   6 m\[Pi]^2 x^2 + 6 x^3) Log[
    1/((1 - x)^2 + m\[Pi]^2 x)])/((1 - x)^2 + m\[Pi]^2 x)), {x, 0, 
  1}, Assumptions -> m\[Pi] > 0 && m\[Pi] < .1]

Version 9.0.1: Version 9.0

But in version 8.0, it works:

Is this a bug, or is the integral really non-convergent? What's a possible workaround, since I don't have easy v8 access?

BTW shouldn't there a space between m and pi, or is this intentional? –  Sjoerd C. de Vries Mar 8 '13 at 22:59
    
$m\pi$ represents a single symbol. –  QuantumDot Mar 8 '13 at 23:00
    
I can reproduce this, but in future, please do not use the bugs tag until a few users have confirmed the behaviour. –  rm -rf Mar 8 '13 at 23:03
    
Thanks for reproducing; I have removed the bugs tag. –  QuantumDot Mar 8 '13 at 23:04

Thanks god 2¤ÇR can't be used as a symbol name –  belisarius Mar 8 '13 at 23:21
