[ZODB-Dev] Traceback with RelStorage 1.4.1 + Zope 2.12.12 + python_memcached 1.4.5

[Sylvain Viollon]

Hello,

  I have a Zope 2, using RelStorage and python_memcached. I use
  python_memcached because I use it in some other extension.

  I got the following traceback on a commit (some objects did
  change, and some where added to the database during the
  transaction):

Traceback (most recent call last):

TypeError: 'int' object is unsubscriptable

  I could not reproduce this error, but still it is worth to report I guess.

  Regards,
