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 general protection ip:41039e sp:7f39e1353328 error:0 in xfce4-mailwatch-plugin[400000+1f000]
I forgot to mention that the version of mailwatch-plugin is 1.1.0
This bug also affetcs me since I upgraded to Xubuntu 9.04. However, with my current configuration (Xubuntu 9.10 on amd64), the bug systematically happens during startup (after login). I can see the mailwatch icon appears in the panel for a second and then it disappears.
I also filled this bug report which shows all the dependencies installed on my computer (since it can also be a Xubuntu specific bug): <https://bugs.launchpad.net/ubuntu/+source/xfce4-mailwatch-plugin/+bug/487080>
While investigating how to reproduce it, I correlated this bug with a mail server malfunction which I observed by receiving a 'Server Unavailable' when using the web-based mail client.
It seems like an unexpected response from the server cause MailWatch plugin to crash. Unfortunatly, I am not able to provide an example of that (since the defunct mail server is now working correctly) but MailWatch crash systematically everytime the mail server was malfunctioning. Now that the mail server is up and running again, MailWatch doesn't disappear from the panel anymore.

This bug affects me too.
I am using xfce version 4.7.0 (git version) on Debian/Sid, PC AMD64, kernel 2.6.32, xfce4-mailwatch-plugin v.1.1.0.
Quite often the 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 will not help either. I can add the plugin back again, but all configuration is lost and has to be done again.
I'm sorry I don't know how to reproduce the bug.

I've been working around this bug for a long time.
Mailwatch segfaults and disssapears once or twice a day --
taking it's configuration down the drain with it.
I finally wrote a shellscript that stops the panel, repairs
both the panel and mailwatch config files, and restarts the
It's sort of a PITA to have to do this all the time...

fixed in verion xfce4-mailwatch-plugin-1.2.0
