I've seen the same behavior when I was witting a lot of files (last time
~2000 files)
following is an strace for nautilus-cd-burner and
nautilus-cd-burner/mapping-daemon during the bugy behavior. I've waited for at
least 3-4 minutes with no response (btw total CPU response was ~1% for all this
time). If you need backtrace please let me know what trick I should use in the
special case of nautilus. I've tried
killall nautilus && gdb nautilus 2>&1 | tee gdb-nautilus.txt
but it captured nothing at all
