Seeing this traceback on a specific whisper file. I can make the file available if it helps with diagnosis.
Traceback (most recent call last):

@obfuscurity, do you still have this issue?
We've seen a similar error from whisper-dump.py when the wsp file has been truncated by a full disk.
There also appears to be an open ticket in the graphite project with identical symptoms graphite-project/whisper#52 (comment)

I'm going to close this out since it seems to be a bug in whisper, not carbonate.
