Buddypress Activity Plus finding incompatibility 3.2 and 3.2.1

I'm having an issue with the BuddyPress Activity Plus plugin with 3.2 and 3.2.1. The conflict presents itself in a Multisite Multi Network installation and shows a 404 error when using the Next/Previous navigation on posts when using Pretty Permalinks (default unaffected, but no good for buddypress).

e.g. http://www.mydomain.com/page/2 redirects inexplicably to http://www.mydomain.com/2/ causing a 404 page not found error.

I discovered this issue by disabling all plugins and replacing one-by-one. This was the plugin that caused the issue.
