Comment 1 Dario Andres 2011-08-07 13:42:53 UTC 
[Comment from a bug triager]
From bug 277891 (KDE SC 4.6.5):
-- Information about the crash:
I did adjust date about 1000 pictures in shotwell and asked it to also change
oryginal files. During process napomuk crashed. Shotwell did complete process
sucesfully.

From bug 276373 (KDE SC 4.6.4):
Downloading website based on wget command described by the link:
http://www.linuxjournal.com/content/downloading-entire-web-site-wget

From bug 278281 (KDE SC 4.6.5):
- What I was doing when the application crashed:
I copied lots of files over ssh with recursive scp-command. Nepomuk has crashed
several times during the copy.

From bug 278280 (KDE SC 4.6.5):
-- Information about the crash:
Transfering a lot of files to the computer via rsync over ssh.

From bug 279368 (KDE SC 4.7.0):
- What I was doing when the application crashed:
I was updating the geolocation of photos on digikam. Digikam was writing the
information to the files when the crash happened.

From bug 275504 (KDE SC 4.6.4):
- What I was doing when the application crashed:
Nepomuk has crashed twice in the past two days. The first time, I was watching
a video on VLC, and the second time, I was talking on Skype. The first time,
every time I tried to restart Nepomuk, it would crash again.
- Custom settings of the application:
Last time kpackagekit was updating this computer to KDESC 4.6.4, it stalled. I
restarted the computer before all of the packages finished installing.
Afterwards, I couldn't see my updates again, so I haven't bothered trying to
get them back. I don't know if this could be affecting my situation or not.

My bad, bug 276373 seems to have a different trace
Comment 8 Dario Andres 2011-08-07 13:49:55 UTC 
Bug 276125 has another cases with a similar backtrace, and mostly the same situation, but including a XIOError

[Comment from a bug triager]
From bug 277874 (KDE SC 4.6.5):
- What I was doing when the application crashed:
Using K3B to rip audio CDs to mp3.  Nempomuk crashes a few minutes into the
rip.  If restarted, it crashes on the next disk.
The crash can be reproduced every time.
