I am having the following issue, where after I drag an email from Gmail onto an item in an outline view, when I click on the email in the outline, it shows the following toast and does not load the email (no, I did not delete the email, it does still exist):

Also when dragging, as @Eik said, when dragging, the email hint/subject appears in the left upper corner until the drag reaches the outline pane.
