Strophe and Roundcube Crash

[Deleted user]

I'm writing a plugin to Roundcube webmail using Strophe. It works fantastically in Firefox and Chrome on Windows and Mac OS but on IE6 and IE8 on Windows XP and Windows 7, just including Strophe crashes the browser with a "stack overflow" error. I don't know which is causing the problem: strophe or roundcube. Any insight into debugging this problem would be helpful! The profiler in IE indicates that it is a problem with an Array.push somewhere but doesn't indicate a line number.
