When I've seen that message, there has always been one or more error messages before to indicate what happened. I suspect you got such message(s) but it got lost in your verbose output. You might try turning off verbose output or redirecting stdout someplace else.
EDIT: You can use the d option if you want to compare the archive to what is now on your file system to find any discrepencies.
