I've managed to replicate this by clicking the 'mark forums read' at the bottom of the main forum page. It seems to be parsing the correct forum display... ie 'do=markread' .... but for some reason the 'do=markread' seems to be set to display the whole forum home page including adverts etc... and not just the forum..... thats where I'd start trying to track it down.... though if this is happening in other places it may not be that.
If anyone knows of anyother place this is happening can they let me know and I'll see if I can replicate it..... the more infomation on where this bug is happening the better when trying to track down these pesky bugs.

Ed,
If you run a slideshow in the gallery it happens (or did do).
Any luck on the 'go to last post' issue?
