Comment 23 for bug 736743

First time trying btrfs and I got the same error right after grub menu:
"error: sparse file not allowed. Press any key to continue ..."

I had another problem with the package apt-xapian-index refusing to configure on upgrade so I removed it and now the system merely hangs on the error above for a few seconds before booting without pressing any key ...

So is this a grub2 bug or a python bug?

Thanks.
