I don't see anything wrong. The output says that your error is zero, are you doing a simple ramp in time? It's very strange that the error is exactly zero. What happens if you just use the default parameters? Does step-52 work correctly? The delta_t_guess is computed around line 715 in include/dealii/base/time_stepping.templates.h You could put a couple of cout there to see what's happening (you will need to recompile deal though)
