[Bug 1389415] [NEW] installer crashes when installing on btrfs

[Andreas Bielawski]

Public bug reported:

When installing Ubuntu 14.10 on a btrfs partition, the installer crashes
when copying data.

This is my partition layout:

/dev/sda1: 173 GB EXT4 partition (other os, ignore)
/dev/sda2: 81 GB NTFS partition (windows)
/dev/sda4: extended
|--- /dev/sda5: 1 GB EXT4 partition (mounted as /boot)
|--- /dev/sda6: 40 GB BTRFS Partition (mounted as /)
/dev/sda3: 4 GB swap

The installer crashes with an "Input / Output Error". The ISO is valid,
I checked the MD5 multiple times and tried with different sticks.
