valgrind backtrace of rebuilding fingerprints

I have to say, that I've never used valgrind before. Thus the attached results
might be wrong.

I worked with yesterdays master (last commit included:
055e495e9ec89806b1d2dd20b1ba9257a04d372d) and recompiled with
CMAKE_BUILD_TYPE=Debug.
Then I launched digikam with the valgrind command found in the HACKING file.
In digikam I selected Tools->Rebuild Fingerprints.

It run for several hours (~10k fingerprints had to be computed).

Well, digikam did not crash.

However, you might find the complete output useful. I stripped the output to be
smaller than 1MB. '[...]' replaces several repetitions of the previous lines.
The logs for configuration, make and install can be found on pastebun:
http://pastebin.com/7dwWBxk8 (cmake)
http://pastebin.com/FCqj3XbB (make)
http://pastebin.com/0AvDdDvr (install)

My assumption is, that this crash only occurs if the fingerprints are not
available at all and have to be build the very first time. In addition, the
crash I experienced above, occurred at about 50% of the process.
