Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8+) Gecko/20020222
I see the same.

My debug build spews assertions continuously:
---------------------------------------------------------------------------------
###!!! ASSERTION: |copy_string| will never terminate: 'count_copied > 0', file
../../dist/include/string/nsAlgorithm.h, line 91
###!!! Break: at file ../../dist/include/string/nsAlgorithm.h, line 91
###!!! ASSERTION: You can't |write| into an |nsWritingIterator| with no space!:
'size_forward() > 0', file ../../dist/include/string/nsStringIterator.h, line 356
---------------------------------------------------------------------------------

Todd: please put "hang" in the Keywords field.

Attachment: stacktrace during hang

Comment 3

[Andrew Schultz]

Attachment: minimal testcase

only contains a !element tag.  These are XML tags (?) that the page assumes
would not be handled by the browser.  The page should instead have:

<!ELEMENT>

The page has invalid tags, but Mozilla should not hang.

Comment 4

[Todd A. Gibson]

added hang to keywords

Comment 5

[gavin long]

I think there's enough here to confirm.  Hang->critical

Reassigning to Evang for the invalid tags issue.

Comment 8

Confirming with Mozilla 099 on Win2000.

Comment 11

[Andrew Schultz]

the given URL no longer contains an invalid ELEMENT tag, and bug 121841, which
was actually causing the hang, has been fixed.

Comment 12

[Frederic Bezies]

Following comment #11, and as I can display this page without problem, I mark
this bug as Resolved Fixed.

Ok ?
