[LMDE] Installing on btrfs stops in the middle of copying files

[Chinoto Vokro]

LMDE 201204 Xfce DVD[i386]

I have a pretty crappy computer (Dell Optiplex GX280) lying around and decided to put Linux on it, and as an after thought, decided to use btrfs for the root filesystem.
Using the partitioning shown below (and a slight variations), I tried to install LMDE several times, but it would just stop at "/opt/thunderbird/libxul.so" or "/opt/thunderbird/omni.ja". I finally decided that btrfs or the installer had a bug, so I tried ext4, which has been working fine so far.

Any further tests by me will not be the same scenario: ext4 partition will be shrunk and btrfs will be placed after it (shouldn't change results though).

Partition Layout: ("_" are for correcting spacing)
---- ---- ---- ---- ----
dev_ | FS_ _ | Mount | Size
-----+-------+-------+------
sda1 | NTFS_ | _ _ _ | 15.00 GiB
sda2 | fat16 | /boot | _0.125GiB (128MiB)
sda3 | swap_ | swap_ | _2.00 GiB
sda4 | extend| _ _ _ | 20.13 GiB
-sda5| btrfs | / _ _ | 20.12 GiB

Install media: ISO on USB booted with Grub2 (The md5sum of the iso is the same as provided on http://blog.linuxmint.com/?p=1979)
grub.cfg: (fromiso was necessary for 201109, but shows errors in 201204, doesn't seem to affect anything though)
