Note:
From this image report, the 'enigmail' leaks should be ignored, at least until the  "core" ones are dealt with.

Attachment: fix

Nulling out msgWindow.msgHeaderSink takes care of securityInfo, too, but it's still appropriate to release this.

fix

I'm fine with this - however, Neil was looking at an alternative fix. It would be nice to add a comment here as well as to why we need to null this out.

(See bug 339072 for its SeaMonkey counterpart.)

This was a false positive, and the report will no longer appear in Leak Monitor 0.3.0.

dbaron, no leak report in POP3 account but with newsgroups there is still this reported problem with Leak Monitor 0.3.

Steps to Reproduce:
1. Choose View -> Threads -> Collapse All Threads.
2. Select thread with answers.
3. Open message in window.
4. Close window.

Reproducibility: Happens sometimes.

Is it the same objects leaking?  If so, reopen this bug or file a new one; if not, definitely file a new one.

Pavel, can you still reproduce this in a current trunk build?

Yes, same result with latest trunk build. I used Leak Monitor 0.3.4.

Comment 12

[Wayne Mery (:wsmwk)]

Pavel, you still get same leak results with trunk?

Comment 13

Now all works fine. No leak report with latest trunk.
