loadvm does not load (offline) snapshot anymore

qemu Version: 0.14.0
The problem is present in the current code from git master as well.

Loading a snapshot that was created while qemu was not running (using qemu-img) does not seem to work anymore.

Using "loadvm <snapshot-id>" in the qemu monitor does not have the desired effect. Not even an error message is displayed.

I was able to track down the problem (using git bisect) to this commit:
http://git.qemu.org/qemu.git/commit/?id=f0aa7a8b2d518c54430e4382309281b93e51981a

After reverting that commit in my local git checkout everything is workin as expected again.
