[ZODB-Dev] ValueError: database_name already in databases

[Chris Withers]

Hi All,

Is this a bug in ZODBMountPoint or ZODB?
In any case, what's the correct tracker to report this in?

Failed to mount database. <type 'exceptions.ValueError'> (database_name 
'packed' already in databases)
Traceback (most recent call last):

ValueError: database_name 'packed' already in databases

FWIW, this is a non-error error. I guess it's trying to tell me that 
whatever is trying to add the packed storage shouldn't be doing it 
twice, but it's only there once in the config. I don't know what's 
trying to add it twice or why...
