If you run just the "Debian Chroot" icon you should get a terminal that shows a bunch of output..

Copy that output and show us here if you can..

Or if it disapears too fast... open a terminal; get to root; and just run "debian" ... see where the errors are.

U didn't need to modify the debian script at all.. if all you wanted to do was mount the img file and copy the data... as root you could have mount myext2.img /debian and copied .. that way not messing with the original scripts... But anyway.. the process you outlined should have been fine.

If you DO get into a chroot using just "debian"... then try launching something from the maemo user account in a terminal like: debbie abiword

Check the output from that command and see where it's failing.
