This is bad, since we unnecessarily consume inodes from root partition or wherever this working_dir is mounted. 

Version-Release number of selected component (if applicable): glusterfs-3.6.0.10-1.el6rhs

How reproducible: Happens every time. 

Steps to Reproduce:
1. create and start a geo-rep relationship between master and slave
2. stop the geo-rep 
3. wait for some time
4. create some data on master.
5. start geo-rep 

Actual results: History crawl consumes zero-byte changelogs


Expected results: History crawl should ignore zero byte changelogs.
