-- Information about the crash:
Computer just booted and Nepomuk crashed.  Nepomuk also crashed as I shut down last night.  This could be an issue with the latest version of Nepomuk because it has not happened before.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault
