encfs 1.7.4

Reproduction:

1. Create new encfs volume in paranoia mode
2. Upload it to DropBox
3. Mount from Android and upload some files (about 300kb, PDF in my case)
4. Result:
   • Uploaded files are partially corrupted! (PDF header is still in place)
   • Trying to open the uploaded files with encdroid results in an checksum error
