(a) Nautilus -> "expert" mode -> customise news sidebar. (b) Added advogato, linuxtoday, lwn, salon and the register. Clicked 'done'. (c) used the scrollbar to go down the sidebar and read headlines. The final entry is the site logo of the register and a very small glimpse of the top of the letters in the top headline of it. If I maximise and then "unmaximise" nautilus with wmaker then it finally notices all the register stuff and lets you scroll down it. If you cannot reproduce, I have a screenshot.
Hrm. I get 'Couldn't load The Register'. However, playing with it a bit more, I can duplicate this with other News sites. Its not a priority for us to fix, so I forwarded it to the Nautilus bug tracker: http://bugzilla.eazel.com/show_bug.cgi?id=8452
