Description

[kevin fisher]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040412 Firefox/0.8
Build Identifier: Mozilla Thunderbird version 0.6+ (20040523)

When composing a reply message, hitting 'enter' key in a block of quoted text
causes Thunderbird to crash.

Not sure if this is the only way to cause the crash, nor if MailNews is not also
affected.

Reproducible: Always
Steps to Reproduce:
1. Select a message
2. Hit 'reply'
3. Move cursor to quoted text (Options -> Quote Message, if auto-quote is not
selected)
4. Hit 'enter' key
5. Observe crash

Actual Results:  
new line is created, followed by crash

Expected Results:  
new line is created, followed by no crash

Wow... how is someone supposed to find *that* bug in a search?!  With such an
obscure summary, it's just asking for dupes.

Makes me feel less silly for filing this, at least.

-> try to reproduce with mozilla mail
(much of the code is the same)
-> crash
-> talkback ID
-> call stack (enter the ID at http://talkback-public.mozilla.org)
-> look at the signature or top function name of call stack
-> search bugzilla with signature/function (both new and recent fixed bugs)
(same callstack means bugs are most likely to be the same)
-> bingo !

Yeah, see, that fails at step 1 seeing how I don't have Mozilla Mail installed
anywhere.  And, judging by the large number of dupes in for Bug 243809, I'd say
that my point is still valid in that the bug is difficult to find with a search
(at least, by a great many folks who submit bug reports) because the summary is
overly cryptic.

Anyway, that's all I intend to spam this bug for -- it's a dupe, and that's
that.  Though, perhaps the existence of this dupe will help others to find the
"real" bug report.

Please reopen the bug, if my last comment is relevant.

Comment 6

reporter: installing mozilla mail isn't hard, and when you're trying to report
crashes if thunderbird isn't giving you talkback stacks, trying mozilla mail is
not remotely unreasonable. as for searching for bugs, it's generally a good idea
to search resolved bugs too, at this point someone could search for duplicates
and find this bug which would lead them to that bug.

the problem is that this bug was basically "if you blink at it wrong, composer
will crash" although bug 244092 might have found it for you.

[e-mail]: you only made one comment on this bug, and it doesn't make
sense without a second.

Sorry, I entered the first comment in Bug #237240,
and the second one here (Bug #244451).  It happened
because Bugzilla automatically skips to the next
bug in the list after a submit.

By the way, both these bugs are suspiciously similar
to my problem, but this one is marked as a dupe of
Bug #244451, which isn't relevant at all (I don't use
gnopernicus).

Comment 8

[Bernie Innocenti]

Please repopen this bug I still see it in 1.5 (20051105).

This time I could reliably reproduce the bug like this:

 - open a draft message for editing
 - insert some characters in a single line
 - mark the line with shift + cursor-down
 - hit ctrl-x to cut the text
 - CRASH!

This is the stack trace I get from gdb:

Program received signal SIGSEGV, Segmentation fault.

there's a deletenode crasher, that's probably the bug you're hitting. but posting gdb stacks for builds where symbols are stripped for talkbakc is fairly silly (really utterly useless). we're not reopening this dead bug. find another one.
