That's a bug introduced a week or two agao; I just fixed it in #3494

[WorldHellow]

Hey I am having the same error. How Can i fix this?

[danpovey]

Bug is fixed; you have to do git pull to get the fix (and recompile in src/ in case the update introduced incompatibilities between the scripts and the binaries.)
