New crash information added by DrKonqi

digikam (2.7.0) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:
when switching through pictures in the editor, digikam always crashes at the
same files

- Custom settings of the application:
well it's a git version (2.7.0). I'm using the git version because of a bug
which caused
digikam to crash when saving an edited file.

Maybe both bugs are relating to each other...

PS: I know that this report is still closed, but... I'm using 2.7.0 ...

"digikam always crashes at the same files" sounds promising: You know a file
with which you can always reproduce this crash when opening it? Which sort of
file is this?

Hello,
I found that the crash while browsing through images in the editor window, has
occurred again in version 2.6.
I can say, however, that it seems like you have to browse through more images
than in order for it to crash than in version 2.5.
It seems like it crashed on files that have been edited, but I am not sure
about that.

Hi there,

same problem here with vers. 2.6.0 (from Debian Sid) -- On some photos, DigiKam
crashes when hitting PgUp oder PgDown. ValGrind output attached.

If this is the crash location, sounds like one of those ever-reoccurring
crashes with the histogram code.

Marcel,

I can confirm that those crashes only occur if the "Colors" tab is selected on
the right-hand image information panel. When selecting other tabs (e.g.
"Properties", "Metadata", or "Caption/Tags"), selecting the next/previous image
from within the image editor works just fine.
