  ProblemType: Bug
  DistroRelease: Ubuntu 11.04
  Package: ubiquity (not installed)
  ProcVersionSignature: Ubuntu 2.6.38-1.28-generic 2.6.38-rc2
  Uname: Linux 2.6.38-1-generic i686
  Architecture: i386
  Date: Mon Jan 31 11:44:55 2011
  EcryptfsInUse: Yes
  ProcEnviron:
   LANGUAGE=en_US:en
   PATH=(custom, user)
   LANG=en_US.utf8

   SHELL=/bin/bash
  SourcePackage: ubiquity

  WORKAROUND:
  Open a Terminal window with Ctrl+Alt+T and do sudo apt-get purge ubiquity-slideshow-ubuntu before starting the installer. This will cause the installation progress window to become very small, but avoid the crash.

  In Xubuntu, please open a terminal, using either the shortcut in the
  panel or Menu button -> Accessories -> Terminal and do sudo apt-get
  purge ubiquity-slideshow-xubuntu before starting the installer.
