digikam (3.4.0) on KDE Platform 4.11.2 using Qt 4.8.4

I added and corected the recogniced names of the face recognition.

Comment 3 aj_ 2013-10-29 16:33:41 UTC 
Thats what I got using the: "valgrind --tool=memcheck --leak-check=full --error-limit=no digikam" command in the terminal. The error in digikam was the same like always but digikam was reacting very slow over the whole time. This is the content from the terminal after the cresh. Dosn't seem very helpfull to me but maybe it is for someone else.

valgrind: m_mallocfree.c:268 (mk_plain_bszB): Assertion 'bszB != 0' failed.
valgrind: This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

New crash information added by DrKonqi

digikam (3.4.0) on KDE Platform 4.11.2 using Qt 4.8.4

I got a error which needed aditional debuging symbols this time. Therefore it seems more like the first error to me. I installed the debugging symbols and got this report. (I was tagging Faces again)
