Please describe the problem:
gthumb --import-photo behaviour has changed from FC6 to F7. For JPG files, the 
modfication time (ls man page nomenclature) is now = to the creation time. This
behaviour results in a loss of the time when the picture was taken. Raw files
import (feature new to F7) shows the correct modification time = when picture
was taken.


Steps to reproduce:

1. Connect camera in PTP mode via usb cable and turn it on
2. gthumb import dialog appears
3. Select photos to import.

Expected results:
Modification time to reflect when the picture was taken not when it was
imported. Consistent behaviour for jpg and raw images.

Does this happen every time?
Yes
