Bug Description

This is no longer a crasher (at least on quantal). On quantal now with the new overlay scrollbars, there is no scrollbar. I get mouse wheel scrolling but never a scrollbar. In quantal, overlay scrollbars was made into a gtk module. If I disable the module, I get a scrollbar.

This is due to the overlay-scrollbars from the PPA being installed, which is now a gtk module. In quantal it doesn't crash, but I get no scrolling.

Leo, I don't think there is anything we can do for this specifically, in the control panel. It seems to almost certainly be an issue in the theme or scrollbar code for the overlay scrollbars.

Ok, I just thought it was weird that it only happens on Ubuntu One. All the other scrolls work without issues.
