Excuse if this is a trivial problem. I have Zope 2.5 on NT 4.0. When I'm working on an object in ZMI and click on the view tab I have a Key error. This looks like a bug (--> file a Collector report <http://collector.zope.org>).
.... File D:\PROGRA~1\ZOPHEL~2\lib\python\Products\Transience\Transience.py, line 133, in new_or_existing (Object: session_data) Here it is checked that the key is not yet there. The test says: not yet there, create it.
File D:\PROGRA~1\ZOPHEL~2\lib\python\Products\Transience\Transience.py, line 159, in new (Object: session_data) Here, it is checked again, before the key is created. This time, the test says: key already there. KeyError: duplicate key 38979001A0LXI.UStIA
This may happen, when two concurrent requests try to create the same key at the same time. For example, from a frame set. The Zope session should protect itself against this quite usual situation... Dieter
