Unexpected zoom while scrolling up/down using my touchpad on pdf viewer evince

[Victor Pallier]

When I use evince to read a pdf file, an unexpected freeze (1-2 seconds) and then a zoom change occur when I sroll up/down.
It only occurs when I use the two finger scrolling option on my touchpad.

I should add that my touchpad was not well supported on ubuntu (ALPS touchpad) before I installed the package available here : http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/psmouse-alps-dkms_0.10_all.deb

I am using the default evince package on ubuntu 11.10.

To re-produce :
* enable two finger scrolling
* open a pdf file with evince
* scroll down and/or up severall times using the two-finger scrolling, the bug should occur.
