Tested on another computer with 2GB RAM, no swap space used but same problem. Nautilus seems to load the whole video file (1.2GB size) in memory, then doing some kind of elaboration which hangs the system. I don't think valgrind log contains something useful, but here it is. I also attached three screenshots from system monitor to better explain what happens.
