I noticed some fun behaviour in Akismet with WordPress 2.5
Every page of spam comment shows the same 50 comments.
It doesn't look like it's pagerizing properly.
This is a clean version of WordPress 2.5 that I downloaded and installed a n exported copy of my blog on WordPress.com. I had to hack the export file because of the 16 MB limitation, so I'm wondering if that caused the problem or if it's a bug with Akismet and 2.5.
