Comment 23 for bug 774978

I don't have the knowledge to know if it's the same bug, but i've got a way to reproduce a similar crash which generates this backtrace:

Steps to reproduce:
 * Install wine 1.2.2 from Software Center
 * Download this minified js that consist in a very large line of javascript: http://bellard.org/jslinux/cpux86.js
 * Second button on the js file -> Open with Notepad
 * Scroll down to the end of the file with mouse or keyboard => CRASH

If you cannot reproduce the bug with these steps or need more info, please tell me.

Besides the bug, 2 things:
 * I opened the file with Notepad because opening with gedit was very slow on opening and moving. Maybe i should file another bug
 * The js is from an amazing Javascript PC Emulator available at http://bellard.org/jslinux. It runs a Linux inside Javascript !!
