I see Chris had an issue with this before, with ZCatalog, but I'm not using ZCatalog.
My system was fine last week. Over the weekend I rebooted the machine (RH 8.0) and
now, one of my top level folders (and all it's children) give this error when I try to "view"
instances of this ZClass based object under this folder.
Details:
Zope 2.5.1 with custom_zodb loading from ZEO (couldn't find the ZEO version, but
ZEO.StorageServer is 1.28.2.5
I have a "Rendered STX" Zclass based on ZObject, ZDTMLMethod, _ZClass_for_Renderable
Instances of this class work fine everywhere in the tree, except for those under
/Research
in /Research and children of /Research, they do not work.
If I copy the instances of this class into another folder (ie. /test) they suddenly start
working again.
I made a backup of Data.fs, then did a pack, then restarted Zope 2.5.1, but the problem
remains.
gzip'd Data.fs is 25 megabytes
2 levels below /Research there is a MountedStorage instance "PythonCE".
--- Attempts to fix --
I created a new top level folder /nResearch
and copied the children of /Research into /nResearch
Now, everything under /nResearch seems to work.. Except for the MountedStorage.
I wasn't sure if the copy process would copy the Mount, or copy child objects of the
mount. so in /nResearch/ ... I deleted the PythonCE folder and recreated the Mount.
However, now when I try to "view" children of the mounted PythonCE under
/nResearch, I get an UnpicklingError.
I'll post the original exception traceback below.
At this point, I am going to move to try to move to Zope 2.6 and ZEO 2, though I
suspect my ZODB is corrupted.

Aha
Seems that /Images/PanellImages is corrupted and can't be loaded in ZMI. So this
appears to be the actual corruption location.
And now /Research/.. PythonCE (the mount) is broken and I get
> The object at
> http://marimba.murkworks.com:8080/Main/Research/Python/PythonCE/PythonC
> EWiki/FrontPage has an empty or missing docstring. Objects must have a
> docstring to be published.
Argh.. going to find the backup tape..
