Added some debugging output to log::LogReader::read

    pub fn read(&mut self, dst: &mut Vec<u8>) -> Result<usize> {

        let mut typ: u8;
        let mut dst_offset: usize = 0;

        dst.clear();

        loop {
            println!("self.blocksize = {}", self.blocksize);
            println!("self.blk_off = {}", self.blk_off);
            if self.blocksize - self.blk_off < HEADER_SIZE {

            if self.blocksize - self.blk_off < HEADER_SIZE {

would you mind trying out what happens if you change this to self.blocksize < HEADER_SIZE + self.blk_off? This would avoid an overflow but should (mathematically) be equivalent.

There is a bug when recovering the manifest, in version_set.rs line ~693. The descriptor_log should be opened using new_with_off to recover the offset.

This is a great find, would you mind sending a PR? (so the credit is yours)
