### Please describe the problem.
The remote server, connected with rsync and with encryption enabled doesn't fill with files.

### What steps will reproduce the problem?
* Add remote server via webapp
* Supply password when asked
* both buttons turn green ('ready to add remote server')
* Select encrypted rsync repository
* When done, files will be queued for transfer, and the queue empties quickly. Afterwards, no files have actually been transferred, but a green message appears and says something like 'synced with xxx'.
* Also, on the remote an empty directory (~/annex) is created.

### What version of git-annex are you using? On what operating system?
local: kubuntu 12.10,            git-annex 4.20130621-g36258de
remote: debian (linux 3.8.0-25), git-annex 4.20130621-g36258de
Both are installed from tarball and PATH is set at the top of .bashrc.

### Please provide any additional information below.

[[!format sh """

Here is what is put in the logs when the button is toggled from 'syncing disabled' to 'syncing enabled'.
