Please provide your failing command line together with the complete, uncut console output to make this a valid ticket.
Is network input / output necessary to reproduce the problem or is it also reproducible with input and output files? Please point to samples if files are sufficient.

Can you try current Git head? I suspect this is the same problem as #2467, and as such fixed now, but you did not provide way of testing.
