The image file is 35335922 kbytes (= about 33GB), but is of course
sparse and actually uses 4218560 kbytes (= about 4 GB). The original
filesystem is 550502400 blocks long (block size 4096, number of inodes:
275251200).

The last few lines of output when using strace:

I can't see what's going wrong here.
