Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.9.97
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Opening a mail in kmail2. 

This crash may be related to the older fixed bug #309551. Perhaps not all functionality was improved to be thread safe or a regression occured?

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