Subject: thunderbird: Segfault on opening mail folder

Date: Thu, 12 Oct 2006 15:56:25 +0200

[Message part 1 (text/plain, inline)]

Package: thunderbird
Version: 1.5.0.7-2
Severity: important

Hi,

on opening my Sent folder, I get the backtrace as attached in thunderbird.bt.
This happens after starting up Thunderbird, opening another folder (the others
mostly work) and opening a mail. Then, going to the Sent folder, the segfault
occurs directly on clicking the folder name.

Other things I noticed are that the problem appeared some days ago after I sent
a mail with 2 attachments (I did something similar some further days ago but
without problem), and the program didn't show the attachment icon in the mail
header list. However, I can even look into the mail on starting Thunderbird
and going directly to the Sent folder. I can even see the attachments. On
manual mail text level, I can't see any significant difference to the earlier
similar mail that worked.

And, I always get

(Gecko:5955): GLib-GObject-CRITICAL **: g_signal_emit_valist: assertion `signal_id > 0' failed

on thunderbird startup.

I can reproduce the problem quite consistently as described. I have my mails on
a (localhost) dovecot IMAP account.

Looking into accessible/src/atk/nsAccessibleWrap.cpp, I unfolded the
GetNativeInterface() call which pointed me to the NS_ENSURE_TRUE() causing a
compiler cast error. Worked around this with a simple comparison. For making
sure and working around new segfaults, I added further NULL checks. See patch
95_accessible_wrap.dpatch. Now, a new segfault (as in thunderbird.bt2) occurs
at nsXULTreeAccessible.cpp:591 where an NS_ADDREF(*aParent), i.e.
(*aParent)->AddRef() seems to dereference a bad pointer. At this point it
becomes a bit complicated...

Maybe a more experienced Thunderbird person has an idea?

I guess Thunderbird confused some internal data structure at some point, and
maybe when I will delete some files in the dotfile dir, I can reset it.
However, thunderbird shouldn't segfault because of this.

Thanks,

bye,
  Roland

Subject: clicking on new message in IMAP folder crashes icedove

Date: Sun, 14 Sep 2008 15:31:53 -0400

Package: icedove
Version: 2.0.0.16-1
Followup-For: Bug #392603

when I click on a new message in an IMAP folder, icedove crashes. If I
right-click and select reply, that works. If I HOLD-click and move it to
a local folder, then I can read it(drga & drop).
