Description

[philippe (part-time)]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20050818 Firefox/1.6a1
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20050818 Firefox/1.6a1

When navigating through pages with forms (the Mozillazine forums, Bugzilla), the
browser crashes when using the back button. Those pages contain forms (textarea,
input[type="text"]).

Fallout of bug 258285 ?

Didn't happen with yesterdays' build (0817).

Sorry, no Talkback ID, the 'Cadence' builds don't include it. I'll attach
Apple's crash log next

Reproducible: Always

Steps to Reproduce:
1. navigate through pages with forms
2. use the back button to go back
3.

Actual Results:  
crash

Expected Results:  
no crash, display page

This happens especially on pages with a textarea (such as forums).

Mac OS X, 10.3.9

Going back and forward between 7 bugzilla bugs WFM.

Bug 258285 was checked into trunk 2005-08-16 10:54 PDT so it can't be it.
This sounds more like bug 304882?  it is currently backed out since
2005-08-18 17:52 PDT so you should be able to tell soon...

Bug 258285 was the first thing that came to mind. I'm never 100% sure what the
actual timestamp is on those Cadence builds (build ID:0000000000). But that is
an other story.

That said, I've been browsing (with the same build as when I filed the bug) with
bfastcache disabled:
browser.sessionhistory.max_viewers: 0.
I didn't experience any crash.

Confirmed on build 2005081901. This is a regression since 2005081801.

Looks like a regression from bug 304896

When I disable Java-Script Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US;
rv:1.9a1) Gecko/20050819 SeaMonkey/1.0a Mnenhy/0.7.2.10005 {Build ID:
2005081906} will crash while using the "Back" Button on every Page. 

Don't know if this was the same Bug, but the Stack looks a bit like this, so I
only add the TB-Incident: TB8523142G
Hope, that the Stack is helpful.

I can confirm this. No JS -> crash when hit 'back' Button in the browser. No
crash, when JS is anabled.

For me this is a blocker for SeaMonkey too!

Could this have been fixed with my recent checkin (to null-check mNavigator)?

Will try this soon, but CREATURE is just not ready with the relevant Build. :-(

Yes, thanks Blake, your Patch has fixed this Issue almost for me using
CREATURE-Tinderbox-Build 2005081911.  Think we can close this one here soon.

(But Bug 305183 is really annoying when I would like to add this here)

This also affected Seamonkey/FF Trunk on Win32.
