Slow simplify[], integrate[] in 5.2 for Mac

Hi All,

I wonder if someone can give some insight into why some simple
calculations are dramatically slower (or don't even simplify) in
Mathematica 5.2 which run perfectly well in 4.2. I'm using a G5 Mac OSX
10.4.  In particular I find the following (artificial) integral:

Timing[Integrate[(a+c-sdfd+34e)Exp[(a+4c-d+34e) x^2+(b-54c+4h) x+c],{

runs in 0.16 sec using 4.2, but >5 sec using 5.2.

Thanks in advance!
