Minions cannot import saved poses

[srik8545-sys]

Steps to reproduce:

1. Summon minion
2. Enable 'Minions' in bone filter
3. Move / rotate minion bones
4. Export pose, and save to a file
5. Select "Import Pose" and select previously created file

On doing this, nothing will have changed, as the file appears to have failed to import. There is no option to 'undo' the file import, and if you had 'redo' steps available before the import (For instance, if you hit 'undo' right after step 4), those redo steps will still be available.
