226898 - META content-type with x-user-defined charset crashes browser

Status: RESOLVED DUPLICATE of bug 210647

(Core :: DOM: HTML Parser, defect)

Description

[jnoyes-sf]

User-Agent:       Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.5a) Gecko/20030723
Build Identifier: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.5a) Gecko/20030723

Loading the above page consistently causes Mozilla to seg-fault.  I grabbed the
page to local disk using wget, and loading it from disk causes the same
behavior.  If I edit out the <META http-equiv="Content-Type" content="text/html;
charset=x-user-defined"> line near the top, the page loads and renders fine. 
Put that META back, and the browser crashes - every time.
I acknowledge that there may be something about my configuration causing this,
but having a more graceful failure mechanism for a configuration problem would
be nicer than the current crash.

Reproducible: Always

Steps to Reproduce:
1. Load HTML document containing tag 
<META http-equiv="Content-Type" content="text/html; charset=x-user-defined">

Actual Results:  
Browser exits abruptly.

Expected Results:  
Rendered the page?  :)

Crash happens with all themes I tried, with/without plugins, with/without
javascript activated, with/without image loading turned on, and with various
cookie settings.

Attachment: REALLY simple html file that also crashes browser consistently

I just threw this example together, so I could confirm it wasn't anything else
about the URL I listed causing the problem.  Even this little chunk of HTML
makes the browser abruptly exit.

Attachment: last few lines of truss output when the crash happens

Sorry, I don't get a core file, so I can't offer much else.

dupe of '[FIX] Crash when trying to change charsets to "user defined"'

this has been fixed since 1.5b
