How did you install Mono 2 on Ubuntu 8.04? Did you pulled it from 
Jaunty? Because as far as I know, the current Mono version on Ubuntu is 
1.9.1, even if you installed the mono-2.0-devel package. Can you please 
confirm that you are running Mono versión 2.0.1 by doing mono --version 
on a console?

I asking because this sound like a double-recursion bug present in older 
versions (up to 1.9.1_2, I think), but not on the current 2.0.1.
I am extensively using ListViews with thousands of items and haven't had 
any speed issue since 2.0.
