/**
 * This test was created to reproduce https://github.com/syncany/syncany/issues/92
 * This bug was caused by an issue in which the checksum of a chunk was used instead
 * of the the checksum of the content. These are the same for small files. Involving
 * some large files and triggering a cleanup caused this bug.
