Mail icon does not appear after boot

[hitech]

I have encountered a strange behavior of the default Mail application.

I've configured the default Mail to download my E-mail from several accounts, including Google. Now, after the boot the icon of the mailbox is not appearing in the Deskbar notification area. This happens regardless of the existence of the new mail messages in the system or on the servers. Mail daemon starts up and downloads the messages, showing the notification, but the only way to get to them is by performing a system query by formula, since the icon is absent.

If I kill the mail_daemon using the process controller, it is relaunched automatically, and the icon shows up, behaving correctly.

Performed a quick search, it doesn't look like this bug is already reported...

x86-64, hrev54106 (but the bug appeared also on the few previous versions).

Additional information: there are 3 mail accounts defined in the Mail Preferences; a Google Mail, a russian Yandex mail (very similar to Google) and the account of my Internet provider. The latter sends messages only in Hebrew, which doesn't seem to be related, but who knows... The mail check period is set to 10 minutes.

I have similar problem on hrev54290. Mail icon sometimes is not present after boot, but it can be recovered by restarting mail_daemon.
