[Evolution] Image preview not scaling

[Wouter van Marle <wouter squirrel-systems com>]

Hi all,

After upgrading to Ubuntu 11.04 I have a big issue with Evolution:
images attached to e-mails are not scaled down to fit in the window
width.

In previous versions large images would be scaled down to fit the width
of the preview window by default, allowing a mouse click to toggle
between scaled and full sizes. Now it doesn't scale at all, just
displays at full size. Very irritating.

How to fix this behaviour, and revert to the old ways?

Wouter.
