big problem when upgrading from2.5.1 to 2.6.1
Hi, After having upgraded from Debian's Zope 2.5.1 to 2.6.1 we encounter a very big problem with some ZClasses of us. As soon as we try to go to the control panel and see our TTW product's content, we've got a traceback like the one attached to this message. It seems that some module's docstrings appear on the stack... I've googled a bit, and found that other people encountered a similar problem when upgrading, but I didn't find any answer. Is this problem known ? Any hint ? (Except doing away completely with ZClasses, which I'm already convinced of) Do you think I can downgrade to 2.5.1 without loosing anything ? (I haven't touched anything yet, doing a backup excepted) Thanks in advance. Jerome Alet

Is this problem known ?
There are known problems with (some) ZClasses when upgrading to Zope 2.6.1. There are solution for them (--> archive). I do not know whether your problem belongs to this class. I miss the "Error Type" and "Error Value" information. Usually, the know problems reference "'iclass' not found" (or something similar). Dieter

No solution for this problem there...

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 Unfortunately the traceback doesn't help me much. 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. Thanks for your help anyway Jerome Alet
