Nope, I have no idea where the hell I read that. I'd try the changelogs of
upstream and the Debian package, however: that rings a bell on my mind.
As for the useful information, that I can help you with. All you have to do
is to let gnupg readd all your keys to a keyring (as in 'new insertions to a
keyring are made in the new cache scheme'). Simple enough to do with any RW
keyrings you might have:
1. move every keyring out of the way, including the RO ones.
2. feed a keyring to gnupg. You might want to use --fast-import followed by
an --update-trustdb for that.
3. replace the old keyring you fed gnupg with with the new one
4. repeat as needed.
I actually find it better to have just one RW keyring, and feed any RO
keyrings I might need (such as Debian's) to gnupg to get them added to that
RW keyring. Since gnupg's handling of multiple keyrings is not really that
hot, keeping track of only a simple RW keyring helps a lot.

Hmm, sorry about that. I sounded far more annoyed/annoying ;) than I should
have.
