images rotated in wrong direction

[gewe]

When I import images (Canon CRW format), the portrait images are rotated
in the wrong direction. In order to show them correctly I have to rotate
them 180 degrees.
This happens when I enable the option Metadata -> "Show images/thumbs
rotated according to orientation tag".

If I disable this option, the images are not rotated (so I have to rotate
them 90 degrees myself).
I don't see this problem with other (non-Canon) software, like Adobe
Photoshop or Bridge.

Is there a way to make digiKam rotate the images correctly without manual
intervention?

I am using digiKam 0.9.1 under Gnome 2.16.1, images were never viewed with
konqueror.

I can confirm this. It works with Krita and showFoto (only the preview is
rotated wrong).

You can download one of the CRW Images here:
http://www.silicoids-world.de/images/2006_01_01__01_06_34__5395.CRW

I'm useing the gentoo ebuilds:

[I--] [ ~] media-gfx/digikam-0.9.1_rc1 (0)
[I--] [ ~] media-plugins/digikamimageplugins-0.9.1_rc1 (0)

The problem has been fixed recently by Andreas in libexiv2. The problem was
that the orientation value in the CRW header was not interpreted correctly.

You happen to know if the patch applies to 0.12 too?  Is it work
backporting the fix to distro pkgs?

It is a small patch which can easily be backported.
