### Please describe the problem.
hasKey check fails when using a Glacier special remote with a non-default region setting.

### What steps will reproduce the problem?
1. Configure a Glacier special remote with a region other than us-east-1
2. Move some files to the remote
3. Somehow let galcier-cli cache expire. In my case this was waiting for more than 60 hours.
4. Try to copy the file to the glacier remote again.

### What version of git-annex are you using? On what operating system?
5.20140227 on Ubuntu 12.04

### Please provide any additional information below.
