Bug 281587

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I have a C++ program that I wrote to open a large data file, process it, and spit out another large data file. This program requires about 2.5 GB of RAM to run. I have 4 GB physical RAM. I was running my program, and the system was under heavy load when the nepomukish crash occurred.

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