[Evolution] Attachment Bar Blanks After Drag Out [Bug?]

[Adam Tauno Williams <awilliam whitemice org>]

Anyone else see this one?   I open the attachment bar of a message
[Before.png] then I drag an attachment out to a folder [into a Nautilus
window, for example] and the drag-n-drop *works* but the attachment bar
goes blank [After.png].  You have to close it and open it again to get
the icons back.
