Caching problem (wrong picture displayed after change)

[Guest]

Unfortunatelly, this is not only a cosmetical thing.

Steps to reproduce:
1) Open a file in the viewer. We need to have at least one another image file in the same folder.
2) Make a change - crop, for example
3) Move to the second file (by pressing PageDown/PageUp or by mouse wheel)
4) Dialog will appear - "Do you want to save changes?" - select "No"
5) Now, you should be viewing second file.
6) Press PageDown or PageUp to move back to the previous file.
7) BUG: Now, we are looking at the changed image, although the changes were not saved.

Apparently, it was saved in a cache. If I change the steps a bit to move to yet another file and then back (changed -> second_file -> third_file -> second_file -> changed), all is ok.

Right, a bug.
