Zimbra 6.0.4 IMAP bug

Has anyone experienced this since upgrading to 6.0.4? One of our directors was talking to zimbra about licensing and was informed about this bug -- snippet below.

We aren't using compression so this won't be an issue for us, but thought it would be good to share with the group.

We're planning to upgrade from 5.0.18 to 6.0.4 this evening.

"The IMAP bug in v6.0.4 I referred to on our call today is "NPE when importing large messages", http://bugzilla.zimbra.com/show_bug.cgi?id=43359
However there is a pretty straightforward workaround for the issue, which is to disable the blob compression:

zmvolume --name volume1 --edit --id 1 --compress false

With that said, Zimbra v6.0.5 is scheduled for January 25th, and we believe will add additional stability and performance."

The work around appears to be pretty straight forward. In the end the 'error' of course is not a real problem since the e-mail and attachment are in fact sent despite the warning to the contrary. Help desk definitely needs to be aware of this warning.
