[digiKam-users] dk 6beta2 portrait orientation problems

[digikam at 911networks.com]

Further info:

The rotating is done by DK6beta2

1. I copied a all bunch of files into one of the directory "watched"
by DK6b2, including about 30 images in portrait orientation
2. DK6b2 first displayed the thumbnail in the portrait orientation
3. after a few seconds DK6b2 processed these images and rotated them
1 by 1 to landscape.

I'm not using DK for any image processing, I'm using Rawtherapee. Is
there a way of disabling image processing in DK?

Thanks
