User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_5; en-us) AppleWebKit/533.19.4 (KHTML, like Gecko) Version/5.0.3 Safari/533.19.4
Build Identifier: 1.9.2.10 - 1.9.2.12

The application crashed during the execution of a nsDOMWorkerXHREvent handler. The reason for the crash is somehow related to the way an array is handled within the handler. There core reason is unknown at this stage.

Reproducible: Sometimes

Steps to Reproduce:
It is possible to reproduce the bug with a specific xulrunner based application. The application is using the standard xulrunner binaries provided by mozilla. Similar crashes has been reported on xulrunner build provided with Ubuntu. Since the specific xulrunner application is composed of only XPI extensions, the crash is probably also reproducible with firefox.

The easiest way to reproduce the crash is to download the following app: http://bit.ly/hiVOHe and execute it with the options listed here: http://bit.ly/dCTE8K
Actual Results:  
The application crashes!

The call stack of JS looks like this:
0 anonymous(webRequest = [object Object]) ["chrome://lite.websecurify.gnucitizen.org/content/imp/lib/lib.webhunt.js":82]
    issue = undefined
    resultSignature = undefined
    result = undefined
    i = 0
    issues = 
    resultsLength = 2
    results = [object Object],[object Object]
    responseParts = [object Object]
    requestParts = [object Object]
    this = [object Object]
1 anonymous(event = [xpconnect wrapped (nsISupports, nsIDOMEvent, nsIDOMProgressEvent)]) ["chrome://lite.websecurify.gnucitizen.org/content/imp/driver.web.js":171]
    observer = [object Object]
    i = 0
    observersLength = 3
    observers = [object Object],[object Object],[object Object]
    this = [object Object]
2 anonymous(event = [xpconnect wrapped (nsISupports, nsIDOMEvent, nsIDOMProgressEvent)]) ["chrome://lite.websecurify.gnucitizen.org/content/imp/driver.web.js":93]
    this = [object XMLHttpRequest]

The affected line is:
				var results       = webanalyze.analyze(requestParts, responseParts);
				var resultsLength = results.length;
				var issues        = [];
				
				var i, result, resultSignature, issue;
				
				for (i = 0; i < resultsLength; i += 1) {

It is unclear at the moment why iterating over the array provided by the function webanalyze.analyze causes the crash. This code is within a function which handles the "load" event of a XMLHttpRequest object. If I remove the loop, the crash doesn't occur. It is also worth mentioning that the crash occurs by just trying to access the very first element of the array. From the stack trace we can see that this element is actually never used in any form within the function. Just accessing the first element causes the crash.

The complete stack trace looks like this:
