I'm using jQuery-2.0.0b1 in an Android PhoneGap app. It works fine under Android 4.0 and 4.2, but testing it on an older Android 2.3 device, it crashes:

03-06 07:35:47.412: DEBUG/CordovaLog(3605): Uncaught TypeError: Function.prototype.apply: Arguments list has wrong type
03-06 07:35:47.412: DEBUG/CordovaLog(3605): file:///android_asset/www/libs/jquery-2.0.0b1.js: Line 5668 : Uncaught TypeError: Function.prototype.apply: Arguments list has wrong type
03-06 07:35:47.412: ERROR/Web Console(3605): Uncaught TypeError: Function.prototype.apply: Arguments list has wrong type at file:///android_asset/www/libs/jquery-2.0.0b1.js:5668

Line 5668 is the "core_push.apply" line in this snippet:

				// Add nodes directly
				if ( jQuery.type( elem ) === "object" ) {
					core_push.apply( nodes, elem.nodeType ? [ elem ] : elem );

				// Convert non-html into a text node
				} else if ( !rhtml.test( elem ) ) {
					nodes.push( context.createTextNode( elem ) );

The bug occurs when attaching jQuery UI Autocomplete to a text input field. The stack trace and code snippet are:

buildFragment(elems=[Object[ul.ui-autocomplete]], context=Document index.html, scripts=false, selection=Object[body]) jquery-2.0.0b1.js (line 5668)
domManip(args=[Object[ul.ui-autocomplete]], table=true, callback=function()) jquery-2.0.0b1.js (line 5516)
append() jquery-2.0.0b1.js (line 5335)

bridge(options=Object { minLength=2, source=function()}) jquery-ui-1.10.0.custom.js (line 506)
render(eventName=undefined) HomeView.js (line 83)

Line 83 of HomeView.js:

this.$( "#title" ).autocomplete({source: filterSuggestions,minLength: 2}); 

I have not included the jquery-ui-1.10.0.custom.js file, but I can supply it if needed.

Adding some console.log() calls at the site of the error to examine the nodes and elem variables gives:

03-06 07:49:26.607: DEBUG/CordovaLog(3791): nodes type = [object Array]
03-06 07:49:26.607: DEBUG/CordovaLog(3791): nodes = []
03-06 07:49:26.607: DEBUG/CordovaLog(3791): elem type = [object Object]
03-06 07:49:26.627: DEBUG/CordovaLog(3791): Uncaught TypeError: Converting circular structure to JSON

So I'm not sure what elem actually contains. On an able-bodied browser, it is:

elem = {"0":{},"length":1}

Please let me know if there is any more information I can supply.
