corrupted usernames

[jlewis@lewis.org]

I've noticed that I'm getting a pretty good number of failed logins with
corrupted looking usernames.  i.e.

Login failure user=t×È^I^I
Login failure user=,¹Ï^I^I
Login failure user=<jÔ^I^I
Login failure user=<jÔ^I^I
Login failure user=^HâÈ^I
Login failure user=^HâÈ^I
Login failure user=<A0>öä^I
Login failure user=<A0>öä^I

horde-1.2.3, imp-2.2.3, imap-4.7c, mysql db.

Anyone else seen this?
