I was able to reproduce this on a Ubuntu 12.10 Live CD (amd64). It can
be seen in the ltrace below that gdk_pixbuf_apply_embedded_orientation()
is called but returns the same pixbuf (no transformation done). In
Ubuntu 12.04 the same function returns a new pixbuf and we can see the
width and length are swapped.
I suspect the image loading module, which should set the "orientation"
pixbuf property, to be at fault. But I would need to run a debug build
on 12.10 to confirm that.

Title:
glslideshow ignores EXIF rotation data from Nikon cameras
Status in “xscreensaver” package in Ubuntu:
Confirmed
Bug description:
On upgrading to Ubuntu 12.10, I find that glslideshow is ignoring
rotation data in pictures taken by my Nikon D7000 camera, and so
portrait pictures are shown rotated by 90 degrees. An example of such
an image is:
http://acunningham.org/photos/2012/06/10/dsc_8639.jpg
Portrait pictures taken by an older camera are displayed correctly. An
example if such an image is:
http://acunningham.org/photos/2003/07/02/France/dsc00112.jpg
This is a regression; it used to work correctly on Ubuntu 11.10.
