Hi All, So, here the story; I have a zodb that's been around for many years. In it, it has a folder containing a few ZPTs and python scripts. This server is now running Zope 2.12. If I zexp export that folder and import into a clean 2.12 instance, the import works fine, but when I try to go to the folder in the ZMI, Zope dies immediately. No messages, no errors, no output. If I delete the ZPTs before the export and import, everything is okay. I can browse the folder and ZPTs fine on the originating server, even after the 2.12 upgrade. I'm left with a vague "wtf?!" feeling. Does anyone have any clue what the problem might be or how I can get any kind of output or error message when it does happen?
