WORKAROUND (from bug #710582):
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.

This bug is very similar in effect to bug #710582, and its listed workaround works (just added to description).

The alpha 2 amd64 image won't install for *anybody* without purging ubiquity-slideshow-ubuntu.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.

Marking this triaged based on the number of duplicates.

 Thanks for taking the time to make Ubuntu better!

So looking at UbiquitySyslog.gz we see the following:

The segfault is with libwebkitgtk-1.0 so I'm going to mark this as a duplicate of bug 710582.
