[Hardy] Eye of Gome zoom doesn't work as advertised anymore

[Rotbart van Dainig]

Binary package hint: eog

Ubuntu 8.04
eog 2.22.0-0ubuntu1

EoG Help states:

You can zoom in or out of the image in the following ways:
    * Use the Ctrl+scroll wheel on a mouse. Scrolling down zooms out; scrolling up zooms in.

HIG states (http://library.gnome.org/devel/hig-book/stable/input-mouse.html.en):

Ctrl+scrollwheel-up should zoom into the window or control under the mouse pointer, and Ctrl+scrollwheel-down should zoom out. Zooming in this way should not move keyboard focus to the window or control being zoomed.

While I'm fairly certain that while earlier in 2.21 it worked that way, now with 2.22.0-0ubuntu1 it's exactly the opposite as described above in EoG:

Moving the mouse wheel up or tilting it right zooms in, moving it down or tilting it left zooms out.

Ctrl+Up scrolls up, Ctrl+Down scrolls down, Ctrl+Right scrolls right... and Ctrl+Left does nothing at all! (In Evince, Scrolling works both vertically and horizontally and CTRL+ zooms.)

[Rotbart van Dainig (rotbart-van-dainig)]

Ok, that Ctrl-Left does nothing is due to the fact that while both tilt directions of the scroll wheel create Button events alone, only Ctrl+Right creates an altered state Button event while Ctrl+Left creates a ConfigureNotify event... like if the window manager grab the event.

Is there a known shortcut on Ctrl+Button 6 or a way to grep for active shortcuts?

[Rotbart van Dainig (rotbart-van-dainig)]

Somehow, /apps/eog/view/scroll_wheel_zoom got set true.

Setting it false recovers intended operation.

Isn't that the default behavior? I have not changed any settings on several Ubuntu installs and they all have /apps/eog/view/scroll_wheel_zoom set true by default.

If that's not supposed to be default behavior, is this not then a real bug?
