Thanks for testing, viewer is early alpha, so it's expected to break. The verbose messages that you posted are quite useful - this means that some block type is not implemented, in this case it's the "usergroup" and "color".

[rusq]

I added support for these two types, it's now in "master" branch, this should fix unsupported block types, and also I'm keen to see if it fixes the panic?

Since I have not received a response, I'm closing this.
