           Summary: nepomuk backup crash
    Classification: Unclassified
                OS: Linux
          Reporter: malte.gerth at googlemail.com
          Hardware: Other
            Status: NEW
         Component: general
           Product: kde

Application: nepomukbackup (1.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
starting a manual backup of nepomuk. after the backup was finished i pressed
the "finish" button and then the crash notice appeared

- Unusual behavior I noticed:
nepomuk is not working properly, as the mailindexer causes kmail crashs and
virtuose-t process is consuming much cpu

-- Backtrace:
Application: Nepomuk-Sicherung (nepomukbackup), signal: Segmentation fault
