442482 - LME reports a transient memory leak when closing 3-Pane window

Status: UNCONFIRMED

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Serge Gautherie (:sgautherie)]

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.

NB:
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):

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

Of course, it can ... after installing LME :->

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.
