I'm not sure, I'll take a look into bugtracker. Anyway, debugger gave me this info: hugin: /home/lukas/DEBUG/test-build/src/hugin-build/src/hugin_base/panodata/Panorama.cpp:1489: virtual void HuginBase::Panorama::setSrcImage(unsigned int, const HuginBase::SrcPanoImage&): Assertion `imgNr < state.images.size()' failed. So it may not be a crash but an assertion error. I don't know what exactly triggers it, but it seems that when I open the GL preview then remove some image, re-optimize it (It's exactly the same process as what I needed for reproduce slowdown in GL preview) then open the preview, select drag and play a bit it aborts. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
