[Bug 894768] Re: Installation randomly fails with: File "/usr/lib/ubiquity/ubiquity/install_misc.py", line 621, in copy_file targetfh.write(buf) IOError: [Errno 22] Invalid argument

[Jean-Baptiste Lallement]

I ran 20 installation of an i386 image and 50% of the tests failed with this error.
I ran the same test with an Oneiric image and none of the test failed.

The duplicate shows that it happens on another environment, and I also
got this error once during an alternate installation. I'm moving this
report to the kernel

  This happens during automated installations but also during a manual
  installation. All the tests have been run on VMs. I haven't found any
  pattern to reproduce this crash and it affects i386 and amd64.

  Running the exact same test again pass most of the time.
