122796 - Scrolling Opsys or Component is crashing mozilla - Trunk [@ handle_gdk_event]

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect)

Description

[Jim Dunn]

If you go into bugzilla and scroll in OpSys or Component, I am seeing a crash

To reproduce:
1) Got to bugzilla/query.cgi
2) Scroll down to Component selection box
3) Start clicking on parts inside of the slider
4) Now click up and down a few times on the arrows.

It hangs pretty consistently.  I even reproduced this while scrolling
in the OpSys category.

No core is created:
I first saw this with my debug build yesterday but can reproduce it with
build id 2002013108 off of mozilla's nightly ftp site.

When I tried to look at this in the debugger, I couldn't get mozilla
to run... so can't provide any useful debugging information

I cannot reproduce this on today's branch builds but it seems to be affecting
others. 

Comment 8

[Jim Dunn]

I didn't try this on today's branch, only on the trunk.

Comment 9

[Hixie (not reading bugmail)]

Why is this event handling and not HTML form controls?
And shouldn't this be a smoketest blocker? I've crashed at least four times
today because of this bug.

Comment 10

[Asa Dotzler [:asa]]

->form controls. smoketest blocker. breaks using bugzilla.

Comment 11

[R.K.Aa.]

Sorry for hitting the panic button: I can NOT make this crash with the latest
2002013108 0.9.8 branch build.

It crashed instantly with what claimed to be 2002013010 0.9.8 branch however:
TB2345262W.  The 013010 build i tested was the sea.tar.gz from
ftp.mozilla.org/pub/mozilla/nightly/latest-0.9.8 (where it is now replaced by
the 013108 build)

related to bug 121011?

Comment 13

[Asa Dotzler [:asa]]

->blizzard

Comment 14

[Asa Dotzler [:asa]]

Looks like the first part of Blizzard's patch for 121011 landed on branch and
trunk  and then the second part landed on branch only a day later(which I'm
guessing explains why I don't see this on today's branch but others saw it on
yesterday's branch).

[Christopher Blizzard (:blizzard)]

Yeah, this is my bug.  The stack looks about right.

Comment 16

[Christopher Blizzard (:blizzard)]

I backed out my patch.  This should be fixed.

Adding topcrash keyword and Trunk [@ handle_gdk_event] to summary for future
reference.
