Comment 7 for bug 3052

Note that this is a side-effect of having a permanent GNUPGHOME in appservers, this problem doesn't happen with the cronjobs (which creates a new GNUPGHOME every run).

My impression is that we could simply modify IGPGHandler.retrieveKey() to accept a 'force' argument which would force it to import the key from the keyserver even if it is already present in the local keyring, and obviously use that for sensible operations like validating keys.

We may find out that we need to re-import keys in many places in order to always use up-to-date keys. In this case we have to investigate the impacts of the extra requests on the internal keyserver (which is single-threaded).
