1. Start to drag a message from the message pane: a little over itself is enough.
2. Cancel the (forbidden) drop, by pressing the Escape key.
2r. Get the following error (same in all products and versions)
{{
Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDragService.invokeDragSession]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://messenger/content/messengerdnd.js :: BeginDragTree :: line 459"  data: no]

NB: Pop3 or Imap4, equally.

Just to confirm I cannot seem to reproduce on Linux with the steps above so seems to be Windows only.

> 1. Start to drag a message from the message pane: a little over itself is enough.

Obviously, Thread pane, not Message/body pane.

New line number is 536.

(SM) Stack is
{{
#0: function BeginDragTree(flavor=string:"text/x-moz-message", selArray=Array:{0}, tree=XULElement:{8}, event=MouseEvent:{0}) in <chrome://messenger/content/messengerdnd.js> line 536
#1: function BeginDragThreadPane(event=MouseEvent:{0}) in <chrome://messenger/content/messengerdnd.js> line 463
#2: function ondraggesture(event=MouseEvent:{0}) in <chrome://messenger/content/messenger.xul> line 1
}}

Code is:
{{
533     dragService.invokeDragSessionWithImage(event.target, transArray, region,
534                                            nsIDragService.DRAGDROP_ACTION_COPY +
535                                            nsIDragService.DRAGDROP_ACTION_MOVE,
536                                            null, 0, 0, event);
}}
That's a C++ function, which Venkman can't step into.
Also, I can't even set a JS breakpoint, as this code is called both when the drag starts and when it's canceled.
(I even wonder if that is the intended behavior...)
