This is with my usual profile,
but not reproducible with dumb Pop3 or Imap4 account profiles.

Moving here from bug 365723 comment 7,
as Unconfirmed until I narrow the (profile) triggering cause.

Leak Monitor extension v0.4.2 reports Leak + Reclaim.
I'd like to avoid this annoyance,
but it's not an actual memory leak otherwise.

(No bug, with my "usual" TB profile...)

1. (re)Start Seamonkey MailNews.
   [Mandatory: bug happens only first time in a "session".]
2. Open Error Console.
   [To have another window.]
3. Ctrl+W (Close 3-pane window), or Alt+F4.
3r. Wait a little, then get leak (and later reclaim):
Leaks in window 0x3220220:
[ ] [leaked object] (3220220) = [ChromeWindow]

Leaks in window 0x3220460:
[ ] [leaked object] (3220460) = [ChromeWindow]
[ ] [leaked object] (33805c0, chrome://global/content/charsetOverlay.js, 240-245) = [Function]
[ ] [leaked object] (33ef320, chrome://communicator/content/permissions/imageContextOverlay.xul, 102-113) = [Function]
[ ] [leaked object] (1e222c0, chrome://communicator/content/viewZoomOverlay.js, 269-274) = [Function]

[ ] [leaked object] (32b1880, chrome://messenger/content/msgMail3PaneWindow.js, 1210-1220) = [Function]
[ ] [leaked object] (32b18a0, chrome://messenger/content/msgMail3PaneWindow.js, 1224-1247) = [Function]
[ ] [leaked object] (32c4b80, chrome://messenger/content/threadPane.js, 43-88) = [Function]

Part of it may yet be related to TB bug 442478.

Maybe worth to test/check if this is would be caused by bug 456672.

It turns out to be unlikely: see TB bug 442569 comment 1.
No longer depends on: 456672
