Not surprisingly because it would be slightly odd to run it on untrusted input, which wasn't just stripped in two. But I have added a couple of robustness fixed that should at least not make= it crash and give an error message that will hopefully explain what is wrong w= ith the input files. --=20 You are receiving this mail because: You are on the CC list for the bug.
