[KPhotoAlbum] Multi-image annotation dialog annoyance

[Reimar Imhof]

Hi,

I've tried a little debugging using photos from the demo annotating all images 
(ctrl-2).
I put a breakpoint in
AnnotationDialog::ImagePreview::PreviewImage::set() in 
/home/<user>/kdevelop/kphotoalbum-5.0.1/AnnotationDialog/ImagePreview.cpp:229

If I do so and go from one image to the next one that breakpoint gets hit over 
and over again for the same file (for example spiff_2.jpeg). I can't tell how 
often, but it's very often... (a hundred times???)
Sometimes the file name somehow toggles between spiff,jpeg and spiff_2.jpeg.

#0 AnnotationDialog::ImagePreview::PreviewImage::set() in 
/home/<user>/kdevelop/kphotoalbum-5.0.1/AnnotationDialog/ImagePreview.cpp:229

#16 AnnotationDialog::Dialog::exec() in

#17 AnnotationDialog::Dialog::configure() in

#19 MainWindow::Window::configureImages() in

#20 MainWindow::Window::configureImages() in 
/home/<user>/kdevelop/kphotoalbum-5.0.1/MainWindow/Window.cpp:425

Now and again I can see the size of the preview area change.
Sometimes it's empty, sometimes it shows a photo (spiff_2.jpeg).
Sometimes that photo disappears immediately - before the debugger hits the 
breakpoint the next time.

I don't know if this helps - well I hope.

Cheers,
Reimar
