Comment 8 for bug 397192

Downloaded the above linked file (4.2GB). When opening the containing folder (icon view, preview enabled) and clicking on the file, nautilus is gone: 100% CPU (actually 50% of my core duo system), ~1GB RAM usage, unresponsive. I've waited half an hour before killing it.

Attaching gdb output while nautilus was hanging (backtrace full, info registers, thread apply all backtrace). Doesn't look helpful to me, but here it is.
