Bug Description

... Firefox crashes on vertical scroll event

I am running Ubuntu Feisty with the latest updates on an emachines m5310 laptop, Athlon, 512MB, synaptics touchpad.

Firefox crashes when I access this page and try to scroll vertically by holding down the left mouse button on the scrollbar and dragging on the synaptics touch pad. It is easily reproducible and fails everytime in the same way. Firefox just disappears from the screen with no crash report, and there is nothing in /var/crash following the crash.

The page that causes the failure is here:

http://item.express.ebay.com/ws/eBayISAPI.dll?ExpressItem&item=130141224199&FROM_MERCHANDISING=1&mode=0&placeid=5

I have reported this before, but it was closed due to lack of debug information. Unfortunately, I couldn't find the old bug that I had reported. Please let me know how to get debug information and I will try to dig it up. Thanks.

Thank you David Watson for submitting this report.

I cannot reproduce your problem (probably because I don't have such
touchpad). I'm marking this report as mt-needtester to see if someone
can reproduce the crash.

However, it could be very useful for us if you please try to obtain a
backtrace by following the instructions on [1], or upload the crash
report that probably was generated during the crash and that should be
located at /var/crash/ to [2].

Please indicate which extensions/plugins do you have enabled; and if
this crash is reproducible describe the steps that lead to it (it is
very important for us to have a test case for each crash).

This will greatly aid us in tracking down your problem.

Thanks in advance.

Hi Hilario,

When this crash occurs, there's nothing written to /var/crash. I followed the procedure in [1], but gdb spits a message that about 486 symbols and I suspect those are not correct for my athlon? Nevertheless, I'm attaching the report so that you can see that I get no stack on "bt full". Let me know if there's something I can do to get better backtrace.

Thanks,
David

Hilario,

I've tested this on a dell poweredge that I have (which ostensibly does not have a synaptics touchpad) and indeed, the crash does not occur. This suggests to me that your suspicions are correct with respect to the synaptics being involved here. I'm also a bit suspicious about the sheer size of the graphic embedded in that page when you scroll. BTW, if that item has expired on ebay, follow any of the new items that look the same, they all crash the same way.

Also, I ran with a clean profile as described in the mozilla debugging instructions, and the crash still occurs without the various plugins.

Your log does not capture a crash at all ... it looks like firefox
exited cleanly.

Are you sure that the session you captured the gdb log from actually
crashed?

(and no 486 is not a problem)

Is this still an issue for you? We are trying to sort this issue and would like to know if this still happens.

If it can still be reproduced, please try to get a dbg backtrace following the steps described at [1].

Thanks in advance.

Hello David Watson,

We have not received any duplicates for some time. Thus, this crash was likely due to some unique plugin extension combination or has been fixed in the meantime. Please, reopen it at any time if you have more related info.

Thanks for your contribution. Don't hesitate to submit new crashes,

H. Montoliu
