Ok, i find the problem, but not the real solution.

I disable OpenMp support to libpgf, and now, it work fine. Thumbnails can be
loaded from database and decoded through libpgf without an error.

As thumbnail process run into a separated thread, using QThread, i suspect a
problem here.

The fact that loadpgdfdata work as well is simple : i do not run in a separate
thead, but in main thread, as it's a single a small test application.

Raphael,

Do you have tested into libpgf test collection tools a case where libpgf is
used through a separated thread, as Posix thread ?

Note that Windows thread as the same problem. It's not Unix thread in this
case...


Marcel,

Another question : image editor use a separated thread to load PGF image. Why
it work fine in this case, if libpgf is compiled with OpenMP support ?
