Mono on OLPC (One Laptop Per Child) device update

Hi guys, A new official version of the XO Operating System is came out some days ago, the 767 build. Unfortunally the mono activities doesn't work on this environment. After some work to understanding the problem (because if I try to run it from Terminal activity using sugar-launch it came up) the bug is now fixed. The problem was related to the rainbow security model implemented on XO. This version of rainbow do not create the standard input and output file handles so the application hang-up. To fix it you need to modify the script that launch the activity to add a redirection from and to /dev/null. After this you have your activity ready to run again. Here you can see the wiki page on laptop.org with the script updated. Happy hacking
