I have experienced the same or similar issue.
Installer crashes after "copying files" stage and at beginning of "installing" stage.
When Slideshow is removed or otherwise not displayed, crash will occur.
However I have discovered that when you wait at "user creation" page, copying occurs/continues in background. When copying has completed in the background and you proceed with user creation, installation stage completes successfully.
