Code review comment for lp:~rodrigo-moya/ubuntuone-client/fix-613219

STR:

1. Disable File sync service in ubuntuone-preferences; close ubuntuone-preferences
2. Launch nautilus
3. Start ubuntuone-preferences.
4. Nautilus crashes:

Looks like "ready" handler is called earlier than nautilus is really ready.
