218628 - Mozilla hangs on keyboard input

Status: RESOLVED EXPIRED

(Core :: DOM: Editor, defect)

Description

[Jukka Ukkonen]

User-Agent:       Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.4b) Gecko/20030509
Build Identifier: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.5b) Gecko/20030908

Almost any keyboard input might cause the similar hang.
Mozilla simply stops reacting to any events what so ever
(keyboard and mouse) and also stops redrawing the screen.
The mozilla-bin binary seems to survive alive, but remains
indefinitely stopped in either select() or poll().

This does not always happen with the first keyboard input,
but given a little time and a few input attempts in can
be invariably reproduced.
Sometimes the problem is triggered while trying to write
to a text box, but also trying to use the arrow keys or
page-up page-down keys to move within the page can trigger
this bug.
Also this can happen either in the browser or in the mailer
window.

Reproducible: Always

Steps to Reproduce:
1. See the detail section.
2.
3.

Actual Results:  
Mozilla totally hangs.

Expected Results:  
Accept the input.

This does not seem to be security-sensitive, removing flag.

Not sure what the correct component would be, starting with Editor: Core.

Reporter, have you seen this with any other platforms? Can you get some stack
traces from the hang situation?

I have this problem too. 
 
mozilla will hang, leaving me with only one option - restarting the computer manually 
(Alt+SysRq+whatever not responding). 
 
this happens on Mozilla browser, MailNews   (V 1.5 and 1.6) and Firebird (V 0.7). 
 
I'm using Mandrake Linux (9.1 Kernel 2.4.21) on an AMD 700Mhz with 256MB RAM. 
 
please ask me for any other info which may help solving this bug, as it is very annoying!!

Attachment: an strace output of mozilla-bin.

this is the output of "strace mozilla-bin" . 
it remains unchanged as mozilla hangs (the last line is the same as it was
before the hang), but dunno.. it may prove useful to someone.....

I can confirm this. (Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.6)
Gecko/20040413 Debian/1.6-5 )

I have had the same Problem on 2 different PC's both using a fresh installation
of debian sarge. If I select any input box or text field the browser crashes and
stops reacting to anything. Epiphany has the same Problem.

upgrading to 1.7beta solved this bug for me, but I still don't know what caused
it in the first place////

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
