[Grok-dev] How do I revover from a CorruptedTransactionError?

[Sebastian Ware]

I have tried:

from ZODB.FileStorage.FileStorage import recover
recover('/Users/jhsware/groksandbox/Rider/parts/data/data.fs')

but I get:

Traceback (most recent call last):
   File "<console>", line 0, in __main__
   File "/Users/jhsware/groksandbox/lib/python2.4/site-packages/ 
ZODB3-3.8.0-py2.4-macosx-10.3-i386.egg/ZODB/FileStorage/ 
FileStorage.py", line 1572, in recover
     npos = shift_transactions_forward(
   File "/Users/jhsware/groksandbox/lib/python2.4/site-packages/

FileStorage.py", line 1460, in shift_transactions_forward
     tl=u64(stl)
   File "/Users/jhsware/groksandbox/lib/python2.4/site-packages/

     return unpack(">Q", v)[0]
TypeError: unpack() argument 2 must be string or read-only buffer, not  
long
