I'm able to reproduce this on a different drive, HDD (WDC WD5000BEVT-22ZAT0), also with data and metadata set to single. There are no problems reported when scrubbing before balance, and then there is corruption reported after balance.
File system is created with: kernel-3.9.5-301.fc19.x86_64 btrfs-progs-0.20.rc1.20130308git704a08c-1.fc19.x86_64 Then updated to: kernel-3.11.1-200.fc19.x86_64 btrfs-progs-0.20.rc1.20130308git704a08c-1.fc19.x86_64 Then scrubbed with no errors. Then balanced with no errors (unlike the previous report with SSD which stopped) Then scrubbed with errors, see below the balance followed by 2nd scrub.
