No solution for this problem there... Wrong! It was discussed several months ago. Anyway, you can look my how-to where I wrote the solution that helped me to cope with some issues: http://www.zope.org/Members/jmeile/upgradingZope
Sorry, it is something like (not at work yet to post the exact message) :
impossible to unpickle object oid "garbage" Error Value : None, traceback may contain clues.
"garbage" is a bucnh of non-printable characters You should search the name of the ZClass that originated the message in the garbage. Then see if it inherits from ObjectManager. If so, see the second point of my how-to.
I've succeeded at accessing it with a 2.5.1 installation, and I've made a backup, now I'll try to reimport into 2.6.1 tomorrow if possible. Actually, that was the solution proposed several months ago. (see my how-to)

So easy when you know what words to search. I think you should add "traceback info may contain clues" in your howto so that googleing for this very specific message would be successfull. Also your solution says "I will assume that you have also a fresh installation of Zope 2.6.0 without anything on it and of course your old Zope 2.5.1". As specified in my previous message, my problem is (was I hope) that I don't have my old Zope 2.5.1 ! This means that your solution, in case I had found it, was unusable at that time, i.e. before I tried to downgrade. Thanks anyway for your very valuable help. PS : I already know who I have to blame for not having a backup, thank you very much. Jerome Alet
