            Bug ID: 339088
           Summary: GIT master: crash when clicking through images in
                    preview, with face recognition running in background
           Product: digikam
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: NOR
         Component: Preview
          Assignee: digikam-devel at kde.org
          Reporter: matthias.andree at gmx.de

Application: digikam (4.4.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was clicking through individual images in the image bar on top, with large
image preview, and I had previously started a face recognition run.
The crash occurred after I have just switched to a new image.

Note the crash handler is launched from Thread #7, trying to acquire an Exif
preview image.

Possible duplicates by query: bug 301045.


Reproducible: Didn't try

Steps to Reproduce:
1. launch face recognition run
2. open some album
3. click one image from overview, and then click through images (to the next)
with the large preview open

Actual Results:  
digikam crashed

Expected Results:  
Git should continue parsing images for faces, and it should display the next
image.

I changed bootstrap.local that I had used for the build, so it's the default
release-with-symbols build, and made two other changes:

 cmake -G "$MAKEFILES_TYPE" . \
-      -DCMAKE_BUILD_TYPE=debugfull \
       -DCMAKE_INSTALL_PREFIX=$DIGIKAM_INSTALL_PREFIX/ \
       -DCMAKE_CXX_FLAGS="-pedantic -Werror=return-type" \
       -DCMAKE_C_FLAGS="-pedantic -Werror=return-type" \
       -DKDE4_BUILD_TESTS=ON \
-      -DDIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=ON \
-      -DDIGIKAMSC_COMPILE_DOC=ON \
+      -DDIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=OFF \
+      -DDIGIKAMSC_COMPILE_DOC=OFF \
       -DDIGIKAMSC_CHECKOUT_PO=OFF \
       -DENABLE_PRESENTATIONMODE=OFF \
       -DENABLE_LCMS2=ON \
