-- Information about the crash:
- What I was doing when the application crashed: I was working systematically through the different aspects of Set Up when the system crashed. I had already downloaded pictures for my desktop, changed the default language from English (US) to Irish (Gaelic) and English (UK) and made a few other small admustments. The precise happenings should be contained in the bug report attached.

-- Backtrace:
