Bug 280443

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-8-generic x86_64
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I was interacting with a konsole when the crash dialog popped up.  I have strigi enabled on a Lenovo T410s, the new telepathy alpha is installed and running, kfilebox, quassel-client, and kontact configured to download calendar entries from a bunch of Google calendars and e-mail from an IMAP server.

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