Raphael,

As you can see in comment #13, OpenMp support from libpgf do not work  in
digiKam.

PGF codec in digiKam will run into a separated thread (QThread class :
http://qt-project.org/doc/qt-4.8/qthread.html) and when libpgf paralellize
decoding to get PGF thumbnail from database, it crash violently.

I written simple a code outside wholde digiKam implementation to reproduce the
problem :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/tests/qtpgftest.cpp

When libpgf do not use OpenMp, all work fine.

I can give you GDB backtrace after that you fix memory corruption/leak
previously listed here. Perhaps openmp has rise up some side-effects.
