When starting evolution once ( after a clean shutdown ), it complained about Missing configuration database. During troubleshooting, I've also run 'bonobo-moniker-xmldb' which hanged, nothing displayed. Please make it work around whatever the problem was, or give more explanations, not hang. oaf-slay run as a regular user gives ( as root there's no error ) panic: end_shift at /usr/bin/oaf-slay line 138. Finally the evolution problem was solved was solved by removing /tmp/orbit-$user and killing all oaf processes by hand. wombat gave no error when started separately. Now bonobo-moniker-xmldb runs ok. So the only reproductible bug is oaf-slay.
With evolution 2.4 should have different bugs. I still get some bonobo/orbit goofiness sometimes, but not reproduceably enough to track down.
