Comment 3 for bug 487080

I have a fresh installation of Ubuntu 9.04 and I am running into same problem repeatedly - sporadically whole mailwatcher plugin just disappears from the panel and will not reappear after loging out from session and then logging back in. Restarting of the panel or reloading the xfdesktop will not help either. I can add the plugin back again, but all configuration is lost and has to be done again. I have used XFCE4.4 for some years before that and never had a problem with mail watcher with same mailboxes in the configuration as now - one gmail mailbox and few IMAPS mailboxes.

All I found in the logs for the last time disappearing was:

xfce4-mailwatch[7909] general protection ip:41039e sp:7f39e1353328 error:0 in xfce4-mailwatch-plugin[400000+1f000]
