345810 - Thunderbird crashes at startup in [@nsTreeBodyFrame::GetIndentation]

Status: RESOLVED WORKSFORME

(Core :: XUL, defect)

Description

[Stephen Donner [:stephend] Not actively reading bugmail]

I'm not sure when this regressed.

Smaug, I'm only cc:ing you because I think you might care or be able to help, not because I think you're the culprit... ;-)

Build ID: version 3 alpha 1 (20060724)

Steps to Reproduce:

1. Start up Thunderbird.
2. Crash, here (but note that this only happens _once_ per _build_, as I use the nightly auto-updater on trunk):

The stack trace looks strange. Does CallGetService use an already-delete-object.
Stephen, is this a new crasher?

CCing bsmedberg, he did something to ProxyObjects lately.

Yeah, it's new.  Less than a week.  I thought it would be so obvious that I didn't file it right away, until I searched Bugzilla and found no reports.

According to talkback, my/the first incident was with the 2006072205 build of TB.

[Olli Pettay [:smaug][[e-mail]]]

Stephen, any chance that you could test that in which build this happens first?

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

Or is 2006072205 really the first build?

I don't know anymore, as I went back to earlier builds (the 20th) and tested again there, but no crash for any build up until even today's.  I don't understand why this seemed to be a transient issue ;-(

I'm going to mark this as WFM; I can't reproduce using the current Thunderbird trunk on Windows Vista, and the reports from Talkback are not only Firefox-specific, but they have totally different line numbers.

The stack I _was_ seeing was consistently different from what few Talkback has.
