Ristretto doesn't rotate with respect to EXIF data

[dark_mail at gmx.net]

Both the versions (didn't test earlier ones) 0.0.14 and 0.0.15 seem to
ignore the orientation information in EXIF metadata, thus not rotating
pictures, although the changelog for 0.0.6 claims different (if I read
that one correctly).

I checked that EXIF data are stored with the pictures (jpeg format), and
manual rotating works.
System is Gentoo Linux 2.6.23

Is that issue known, or is there an error on my side?
Can give more info if needed, after a cup of sleep ...
