I confirm what Peter says.
I've always seen exactly this behaviour, turn 90° counter clockwise
or 180° clockwise. And not « often » as said Kai but « always ».
(With all DK versions I've used, from 1.3 to 2.6.)

(I found a bit strange to provide a 180° rotation, because
holding a camera with top down and bottom up to the sky,
to shoot something that would require a 180° rotation is not that
common:-) Most portrait oriented images require +90° for right
eyed users, and -90° for left eyed users.)

Anyway I didn't care much, mostly for the reasons stated by JD.

I agree. Looks like not all software behave the same, regarding
images rotations. Neither do all images albums web hosting

Also, when one derive an image variant without Exif information
(what I do for e.g. small versions for web pages thumbnails),
all flags are lost and only a correctly oriented pixels matrix
can lead to correct display.

So I rotate myself, with image editor, and leave Digikam in
« do not show rotated » mode. Don't know if there's a better
