I think BTrees still have some bugs. 2.6.1 has a workaround for this very issue, or you can just replace the Transience package itself from CVS. On Tue, 2003-02-18 at 17:01, Alan Runyan wrote:

in a Product i'm using/wrote... we try to get the SESSION.getId() and get a KeyError. Here is the traceback. I would appreciate any feedback. Many thanks.
# gc the stale buckets at the "beginning" of _data ("garbage collect") # iterate over the keys in data that have no minimum value and # a maximum value of delete_end (note: ordered set) # XXX- fixme. range search doesn't always work (btrees bug)
I believe it is the line after this that is throwing the exception for k in list(data.keys(None, delete_end)):
here was the exception:
Site Error
An error was encountered while publishing this resource.
KeyError Sorry, a site error occurred.
