This is probably due to the final argument being a character string which PETSc has difficulty managing by default for Fortran.
I just removed the format argument from the call so this problem will gone soon. You could just comment out the call for now and put a print statement in instead. The problem will be fixed as soon as my merge request gets into master. Sorry about this.
