Version:            (using KDE 4.4.2)
OS:                Linux
Installed from:    openSUSE RPMs

When I modify file "A.jpg" in Gwenview for e.g. using "Mirror" operation, and try to save file using "Save As" then file is saved correctly as "B.jpg". The information "You are now viewing the new document..." is displayed. In the window title "B.jpg" is displayed. Next  I try to modify this picture using some other operation like "crop". Everything is ok, and when I save file using "Save" no error appears. In the window title  still "B.jpg" is shown. When I close gwenview and open A.jpg, I see picture which should be saved as B. So original file was overwritten !

In the console I can see information:

gwenview(21023) KFileItemPrivate::init: "A.jpg" does not exist anymore                                                                                
gwenview(21023) KFileItemPrivate::init: "A.jpg" does not exist 
anymore                                                                                
gwenview(21023) Gwenview::MainWindow::goToUrl: KUrl("file:///usr/local/Biblioteka/Grafika/Zdjecia/B.jpg")

Program exhibits different behaviour when after saving A.jpg as B.jpg i try to zoom it. Then it hangs and after some time crash with information displayed on the console:

gwenview(20219) KFileItemPrivate::init: "A.jpg" does not exist anymore                                                                                
gwenview(20219) KFileItemPrivate::init: "A.jpg" does not exist anymore                                                                                
gwenview(20219) Gwenview::MainWindow::goToUrl: KUrl("file:///usr/local/Biblioteka/Grafika/Zdjecia/B.jpg")                                          
Segmentation fault

I thing this is very sever bug. I lost a few original "A.jpg" files. I could reproduce it on two opensuse11.2 + kde4.4.2 installations on two separate computers.
