Public bug reported:

Release: Ubuntu 11.10
Package ver: 3.2.0-0ubuntu1
Expected behavior: When two-fingered scrolling is enabled, a two-finger drag should smoothly scroll the document
Actual behavior: The view jumps to the end-point without scrolling.

Additional info:  Input device is a BCM5974 on an Apple Macbook Air 3.1.
Behavior returns to normal when I download the source package and
rebuild without the libgrip patch, so it's definitely a bug in the
interaction with the utouch stack.  Other multitouch (libgrip/geis)
gestures (pinch-to-zoom, twist-to-rotate) work just fine.  Switching the
touchpad to edge-scrolling works fine.
