Bug 291083

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Linux Mint 11 Katya

-- Information about the crash:
- What I was doing when the application crashed: I have Google Chrome, Minitube 1.6 or 1.7, and Dolphin open at the same time. I can start a download using Minitube without a problem, but when the download finishes, Nepomuk Stub crashes. If I have mulitple downloads going, Nepomuk crashes as each file finishes. I have always downloaded large files 200MB or bigger, so I don't know if smaller size files do the same thing.

The crash can be reproduced every time.

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