442478 - LME reports a transient memory leak when closing 3-Pane window, with these steps

Status: RESOLVED INCOMPLETE

(Thunderbird :: Mail Window Front End, 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 13,
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.

1. Start Thunderbird.
2. Open Error Console.
   [To have another window.]
3. F8 (Close Message Pane)
   [Only to confirm that Message Pane (content) is not a trigger.]
3. Select a (empty) folder.
4. Ctrl+W (Close 3-pane window), or Alt+F4.
4r. Wait a little, then get leak (and later reclaim):
