[ZODB-Dev] Is this a bug ? [ZODB3-3.10.0b8]

[steve]

Hi,

We recently updated the zodb package to ZODB3-3.10.0b8 on our servers which
serve a repoze.bfg application with a ZODB backned. Since then some methods
which worked before the update have been failing with traces similar to this:

(also at http://pastebin.com/aPKwBQp6 , in case that is easier to read)

  SystemError: new style getargs format but argument is not a tuple


I just wanted to confirm whether this is something to do with the app or a ZODB 
bug. Any pointer/help would is appreciated.

cheers,
