Comment 6 for bug 1308833

I have the same problem with an Asus Eeepc running Ubuntu 12.04LTS (32 bit) & Windows7.

It occurred today when I updated from kernel 3.11.0-19 to 3.11.0-23.20 & then tried to use GC to tidy up the grub screen.

Failed saving grub configuration!

Please take a look at the command line output below. If you think this is a bug of Grub Customizer, please create one at https://launchpad.net/grub-customizer! Generally Grub Customizer should prevent errors like this.
