Bug 279180

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:

I asked Eclipse to refresh and clean all projects (about 10+ of them). This service seems to have real issues when I do something I/O-intensive like that.

The crash can be reproduced some of the time.

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