--- Comment #2 from Gilles Caulier <caulier.gilles at gmail.com> ---
Marcel,

I can reproduce the crash here. Whithout to change any settings in Restortation
filter config, let's filter processing image until end, and  at 99% it crash :

(gdb) bt

It sound like it try to emit finished() signal and end through
dimgthreadedfilter.cpp:199. Perhaps filter instance is go out quickly from
memory ?
