I also got this error, but at the beginning of the installation process. Since nothing had been installed I had no way of attaching any files. The only thing I noticed that might be helpful was the message "out of disk space" at the end of the trace, despite the fact that my root partition had 8GB.
I now have no way to continue the installation, which is quite frustrating. -- the installer crashed https://launchpad.net/bugs/95300 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
