Problems with message creation (Zimbra 6.0.8)

[HidX]

Greetings.

Yesterday it was updated with Zimbra 6.0.7 on 6.0.8 (OSE Debian Lenny). There was a small problem.

If I after creation of the new message, switch between tabs, and then I am again returned back to the message created by me there is an error.

In broad gulls anything suspicious hasn't noted.

Probably it is important. But yesterday I have installed on the server zimlet, there can be this all from for it? (Though and without it too there is an error)

Help please.

Today has tried to do these operations in Firefox. The error as appears but with more detailed description.

Look a screen.

Similar problem all the same in zimlet.

Prompt please, what it is possible to make here?

Thanks!
