This seems to be a non-bug. Following order is required to use incremental backup:
1. Do full backup.
2. Run apply-log on full-backup.
3. Create some tables and add data, then take incremental backup.
[ Step 2 and 3 can be in any order ]
4. Run apply-incremental-backup operation to apply incremental backup
on full backup. [ Prior to 3.6, this operation was called
--apply-log --incremental ].
There are 2 important things to note:
(1) The step-2 in above is required. i.e. You should run apply-log on
full backup before considering applying the incremental backup.
(2) you should not run, --apply-log on incremental backup itself.
The destination repository for apply-log is always full-backup.
Please clarify if the above procedures were followed. Also, if you think the documentation for above is not clear, we should fix it accordingly.

Also I wonder what server version you were working with.

Valeriy, I am using mysql-5.1 server (i.e mysql-5.1-meb tree)
