Bug 279535

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

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

I was using vim in two different konsoles, on two different desktops, no other programs open or running, although I had earlier changed the nepomuk settings in system settings,(changed the memory usage), as I'd noticed nepomuk had constantly stopped indexing files for several days, since the kde 4.7 update.

- Unusual behavior I noticed:

The Nepomuk icon appears/disappears randomly from the panel, and the osd pops up to tell me that file indexing is suspended because of system resource problems. The "system activity" monitor constantly shows virtuoso-t as running at 25% - 30% of cpu, and memory at about 480.000k.

- Custom settings of the application:

Since the kde 4.7 update I have changed the settings :-

memory to 1000MiB

I've also removed some of my files from indexing

The crash can be reproduced some of the time.
