KDE Platform Version: 4.4.1 (KDE 4.4.1)

Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I have set KGet to exit when there are no active downloads. I also have KGet tag my downloads with Nepomuk semantic information.

KGet crashed while exiting and looking at the stack trace it seems that it could be related to Nepomuk.

 -- Backtrace:
Application: KGet (kget), signal: Segmentation fault
