Short description of error
When exporting a scene with a camera, geometry will be randomly transformed.

Exact steps for others to reproduce the error
Open Attached file, export with this settings:

This is the original ( and the result of export + import when camera isn't selected)

This is the original plus the result of export and import (when the camera is also exported)

Do the same thing without the camera selected and export will be good... for some reason.

Thanks for the report but it would be helpful if you add a blend-file to the report that demonstrates the issue at hand.
I could not reproduce this behavior when i export a simple scene with camera and 2 objects.

oups sorry

After testing many versions, Bug is already present in 2.74.

the problem was that as soon as animations are exported the Exporter enforced the decomposition of Object matrices into Location and x/y/z rotation. It looks like this decomposition is obsolete, so i removed it. Now the export/import of the scene seems to work as expected.

I also tested a character animation (export/import back) and that seems to work as well.
