SentEmailViewerPlug shows empty emails with Dynamic Templates & LocalAdapter

[Calamari]

I tried it with version 2.1.0 and 2.2.0 but if I try sending emails using the LocalAdapter. The viewer is showing that there is an email, but it is always empty.
But if I use the actual Bamboo.SendGridAdapter, it sends out the Email flawlessly.

This makes development and test environment particularly undesirable. Anyone an idea what the problem is? Am I the only one having this?
