601897 - Browser crashes when you select a drop-down list

Status: RESOLVED DUPLICATE of bug 550392

(Core :: Widget: Cocoa, defect)

Description

[Richard]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 FirePHP/0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 FirePHP/0.4

When you select the drop-down list, the browser crashes. I have used the Jquery plugin Uniform (http://pixelmatrixdesign.com/uniform/) to style the form elements but this seems to crash the browser. I have checked on Safari and it worked ok. IE on mac and PC was fine. Chrome was a bit jittery but still worked. Firefox 3.6.10 on PC just didn't show the list. Only Mac Firefox seemed to crash the browser.

Reproducible: Always

Steps to Reproduce:
1.Load the page http://sbgi.tapdev.co.uk/events/content/179/utility_street_works
2.Select any of the drop-down lists under the heading `Utility Metering`

Actual Results:  
The browser should crash

Expected Results:  
The list of products should be displayed

I am using jquery to check the state of the drop-down, to enable the add to order button. 

I am also using a flowplayer plugin called overlay but this is not working on the drop-down lists but on the share button

It also crashes a recent mozilla-central debug build on OSX.
It does not crash on Windows or Linux64, but the dropdown menu
does not appear when clicking the combobox.

I can also easily reproduce this, in FF 3.10 on OS X 10.5.8.

This bug is a dup of bug 550392, but has much better steps-to-reproduce.
