New posts duplication after ajax refresh (0.3-stable)

[tco_tm]

I am getting duplicated new messages on the list, but only after ajax refresh. Clicking INBOX folder in the tree will generate proper view.

I can not find related active ticket in bug tracker. Is this problem known and/or is there any solution?
