When viewing a webpage and using Songbird, X suddenly crashed (I think it's X that crashed, as the screen suddenly went blank, my music stopped, and I was sent back to the gdm login screen). I'm using Karmic 64-bit, kernel 2.6.31-16.53.
This was in dmesg: (I will include the complete file as an attachment)

It just happened again, this time dmesg only contains an ACPI Warning, so I doubt it's Compiz-related:
kernel: [20920.389627] ACPI Warning: \_SB_.PCI0.
