Doh! This is a dumb bug. Please apply this patch to TemporaryStorage, and this bug will go away. This will be in the next 2.5 beta release (or final if no betas in the interim).

Hello all,

I have some problems using the Session Data Manager in Zope 2.5.0b3. Sometimes I become a Unpack error. Here is the traceback:

Traceback: Traceback (innermost last): File /home/zope/Zope-2.5.0b3-linux2-x86/lib/python/ZPublisher/Publish.py, line 103, in publish File /home/zope/Zope-2.5.0b3-linux2-x86/lib/python/Zope/__init__.py, line 172, in commit File /home/zope/Zope-2.5.0b3-linux2-x86/lib/python/ZODB/Transaction.py, line 233, in commit File /home/zope/Zope-2.5.0b3-linux2-x86/lib/python/ZODB/Connection.py, line 347, in commit (Info: (('BTrees.OOBTree', 'OOBucket'), '\x00\x00\x00\x00\x00\x00\x00*', '')) File

What is the problem?
