Raphael,

As you can see in my last comment, i commited last code from libpgf repository
and recompiled digiKam. Running it through valgrind report again some issue
about memory problems. Below, it's not a memory leak :

At end of application, valgrind report memory leak. It's not too huge, because
i stopped thumbnail maintenance task 30 secondes after to start (1%
completed)...
