Hi Stefan,

I already had this bug once and after a unmeasurable period (days or even
weeks) and a reboot of the VM, the FS was back.

"all seems OK" means the QED file is not corrupted and consistent. I still
have files from 8 Oct 2012.

  This night after a reboot of a VM, it was back to 8 Oct. 2012, i've
  lost all data between 8 Oct 2012 and now. I've check the QED file and
  mount on another VM, all seems OK.

  This QED has a raw backfile with the base OS (debian) shared with many
  others QED. It has NO snapshot.

  QEMU emulator version 1.1.2

  Does anyone have a hint ?
