347890 - Firefox crashes browsing "Penny Arcade" after latest patch [@ libflashplayer.so]

Status: RESOLVED WORKSFORME

(External Software Affecting Firefox Graveyard :: Flash (Adobe), defect)

Description

[u71076]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

After the latest patch (version 1.5.0.6) was applied to my Firefox install, the browser now crashes if I try to browse the Penny Arcade website (http://www.penny-arcade.com). 

I don't know how helpful it is, but these crashes have been submitted via the "Mozilla Quality Feedback Agent" with Incident IDs such as TB21873076E, TB21871752Y, and TB21873091Z.

This crash is happening every single time I try to use the Penny Arcade site with the new patch. In the course of testing steps for this bug, I just crashed the browser a couple dozen times.

Reproducible: Always

Steps to Reproduce:
An example of "browsing" which causes a crash:
1. I have http://www.penny-arcade.com/comic set as one of my homepage tabs.
2. From this page, click the "Penny Arcade" banner which links to http://www.penny-arcade.com
3. If this doesn't cause a crash, click one of the hyperlinks in the text. For example, the front page currently contains a link to http://www.penny-arcade.com/comic/2006/08/07

So you're crashing completely within Flash. I find it really hard to believe that upgraded along made this start crashing.

Can you download 1.5.0.4/5 and see if it was indeed a regression?

(Somehow I think I downloaded an Arabic version of 1.5.0.4, which was a fun experience...)

I couldn't get the browser to crash on 1.5.0.4. On 1.5.0.6, it's still trivial to crash it.

If you're not able to reproduce the problem on 1.5.0.6 is there some way I can turn on debugging to produce a stack trace?

I am finding a very similar thing. Penny-arcade causing all instances of firefox to disappear - usually when I open the latest comic in a tab. It does not happen 100% of the time and it has only started doing this recently (last month or 2).

Firefox 1.5.0.5
Ubuntu Drapper (with all the latest updates) - 2.6.15-26-386


I'm happy to do tests (stack traces and such) by request.

You should be able to grab the Firefox debug package from Ubuntu (firefox-dbg or something). This will give you debugging symbols for Firefox. 

Then you can do something like:

./firefox -g -d gdb
handle SIG33 noprint nostop
run
<crash>
where

That should give you a stack (with symbols, hopefully) that you can paste or attach to this bug.

I'm just running Firefox that I downloaded from mozilla.com (firefox-1.5.0.6.tar.gz). I've looked around on the developer pages, but I haven't found a similar 'debug' download. Could you provide a URL?

Comment 6

[Adam Guthrie]

Ah, sorry. I was assuming you were using the Ubuntu Firefox package. If you're not using a package, you'll have to compile your own debug build, which isn't all that easy...

Also occurs on latest stable Mozilla (1.7.13).

I did a quick search in Synaptic and it looks like I've got a few flash things installed. How do I know which one Firefox is using? 

Incidently, I've started using Epiphany, and I can browse Flash sites fine with it.

You can find the information on the plugins info page. Enter 'about:plugins' into the location bar and search for Flash.

flash v7 for linux is known to crash.

current version is Flash 9.0 r31
does it solve your crash?

I haven't seen this crash since upgrading to Flash 9.0 r31. WORKSFORME?
