Ok, the good news is that this seems to be the problem.

unfortunantly the skiplist recovery tool is not working.

# ./skiplist.py dlang.seen.bak >dlang.seen.txt
Traceback (most recent call last):
   File "./skiplist.py", line 172, in <module>
     values, keys = getkeys(fp)
   File "./skiplist.py", line 152, in getkeys
     spointer = unpack('>I', str_p)[0]
struct.error: unpack requires a string argument of length 4

# file dlang.seen.bak
dlang.seen.bak: Cyrus skiplist DB

I tried enabling debug mode in skiplist.py and I'm not seeing anything 
different. This confuses me. I'm not that familiar with python, but as I read 
the code, get_header() should be writing a bunch of stuff before it gets to the 
getkeys() section that failing.
