Q: Unexpected crash 10.9.1 - help reading logs?

My computer crashed sometime last night. I had set my iPad to sync a playlist from iTunes and then in the morning my computer was off. It has crashed and rebooted overnight. Below is a Kernel Panic report from 2014-01-31-083441 when I turned the computer back on this morning. Anyone able to help me diagnose what went wrong? Thanks in advance. NL
