Easystroke doesn't recognize button release

Binary package hint: easystroke

After todays upgrades easystroke stopped working properly.

When I start a gesture it draws the correct movements on the screen but fails to recognize when I release the mouse button and therefore doesn't execute the command for that gesture. Instead it keeps on drawing the gesture until I hit a button (another or the same) to cancel the gesture.

Exactly 50% of the time the gesture fails to start and instead a right click gets executed, if mapped to the right mouse button. If mapped to any other mouse button, the gesture starts every time, but still fails to stop on button release.

Simple clicking the right mouse button also starts a gesture 50% of the time, no different to holding that button.
Clicking with any other mouse button starts the gesture every time.

Using: Ubuntu natty, up to date
compiz or metacity, makes no difference

Among todays upgrades were xserver-common, xserver-xorg-core and xserver-xorg-input-all
