bugs_examples vol1 dogs doesn't run. I've verified that it results in:

Initialization between (-2, 2) failed after 100 attempts. 
 Try specifying initial values, reducing ranges of constrained values, or reparameterizing the model.
[1] "Error : "

This should be fixed. It used to run a long time ago.
