            Bug ID: 321680
           Summary: crash / segmentation fault when trying to recognize
                    faces
    Classification: Unclassified
           Product: digikam
           Version: 3.3.0
          Platform: Compiled Sources
               URL: http://paste.kde.org/~digikam/784166/
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: libkface
          Assignee: digikam-devel at kde.org
          Reporter: bugtrack at web.de

3.3.0-beta2 sources (tarball), compiled on gentoo linux, were used to test the
recognition feature.

However, recognition did not work in my case yet, as digikam crashes
reproducibly just after clicking on "Scan" button (after selecting Recognize
radio button).
The face detection however is successful (but that was already the case before
3.3).

Reproducible: Always

Steps to Reproduce:
1. start digikam
2. (detect faces, tag some of them with names)
3. let digikam recognize faces => crash
Actual Results:  
digikam crashes (segfault).

Expected Results:  
no crash, but successfull recognition of faces

The crash is even reproducible when running digikam under gdb, see
http://paste.kde.org/~digikam/784166/

Fatal Error: Accessed global static 'FileReadWriteLockStaticPrivate
*static_d()' after destruction. Defined at
digikam-3.3.0-beta2/core/libs/threadimageio/filereadwritelock.cpp:385
