** Summary changed:

- qemu-img convert: error while reading
+ qemu corrupts qcow2 image

** Description changed:

  Binary package hint: qemu
  
- I try to recompress a qcow2 image that apparently is perfectly working,
- but qemu'img writes out about 60kB and, after about ten seconds spits an
- error. This is the first time this happens, few days ago I had used
- regularly this same command to compress old versions of this image.
+ Qemu 0.10.0 occasionally corrupts qcow2 images.  The problem should be
+ solved in 0.10.2.
  
- This is qemu 0.10.0 from Jaunty. If necessary, I could provide the
- image.
+ This is how I observed it the first time:
  
  $ qemu-img convert -c -O qcow2 wxpsp3-wlm-noacpi.qcow 
wxpsp3-wlm-noacpi.copia.qcow
  qemu-img: error while reading
  
  $ qemu-img info wxpsp3-wlm-noacpi.qcow 
  image: wxpsp3-wlm-noacpi.qcow
