Using gentoo. This happened while I was connected as invis with the MSN protocol (and taking a shower!), so the probability of external input seems minimal, at best. These crashes did not happen with 4.3 as far as I can remember, but in the last 2-3 days since upgrading Kopete has crashed about once/day.
