[Bug 979350] Re: install with encrypted home failed near the end: OSError: [Errno 12] Cannot allocate memory

[Colin Watson]

I don't know if this will make much difference, but worth a shot if the
slideshow is responsible for that much:

ubiquity (2.10.12) precise-proposed; urgency=low

  * Fix download verification to handle epochs correctly, and add a little
    more logging so that we can debug any further errors along these lines.
  * GTK frontend:
    - Disable WebKit's cache, since the slideshow doesn't have a significant
      browsing interface and the cache is memory-hungry.  This may help with
      LP #979350.

Bug description:
  I was trying to recreate another bug and just a full disk install with
  an encrypted home and received a notification that ubiquity had
  crashed.

  TEST CASE:
  1. Use a system with 1GB of RAM or less or a VM and set Virtual Memory to 1024MB
  2. Boot a Live Session
  3. Start Ubiquity
  4. Select the following options:
    - prepare: select 'Download upgrades while installing' and 'Install 3rd party software'
    - partman: use entire disk
    - user setup: Encrypt my home directory
  5. Proceed with installation

  ACTUAL RESULT
  Near the end of installation ubiquity crash with the following error in syslog:
