Description Chris Samuel 2010-06-14 13:26:39 UTC
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Just started uploading photos from my Nikon D90 via Digikam when I received the notice that nepomukservicestub had crashed.  This hasn't happened when previously uploading with the same versions so that may just be a coincidence.

KDE 4.5.0 beta 2 from the Kubuntu PPA repository.  Digikam 1.2.0 from the same.

nepomukservicestub (0.2) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.7.0

- What I was doing when the application crashed:
I had just pressed F8 in KDevelop.  It saved the modified files, nepomunk crashed, and then the build started.  The timing may have been coincidental, or perhaps something to do with modifiying the files?
- Unusual behavior I noticed:
The system was running slowly in the moments before the crash.

I had multiple tabs open in Firefox.  I went to my system tray to open Clementine and Nepomuk crashed.  It seemed very out of the ordinary and I really wan't doing anything I hadn't done a hundred times before.

From bug 262474:
- What I was doing when the application crashed:
I had just opened Picasa, which indexed a lot of files as it had not been
opened for a long time. In picasa I selected "Create" --> "Picture Collage.."
At this point (within a blink of an eye), the bug reporting tool was
instigated.
I tried to repeat two times unsuccessfully, but something changed as on the
third time I tried to open the picasa programme, it also crashed.

From bug 269600 (KDE SC 4.5.5):
- What I was doing when the application crashed:
I was doing an rsync -avr from an external usb HDD to an on board SATA HDD. 
I then opened a terminal and sudo'd to rm -r the directory that rsync was
writing into.
Halfway thru the deletion process I issued CTRL-C  to the terminal running  rm
-r.
That is when nepomuk seemed to crash.

Comment 20 Jacob Godserv 2011-07-05 17:12:18 UTC
Oh wow, I just realized that Ark didn't finish extracting either. That was odd. I tried running Ark again, exactly as I had done before, and it extracted the entire thing, without any crashes.

New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.2

- What I was doing when the application crashed:

Simply staring at my desktop. I was mousing over icons, thinking about what I wanted to do next, when suddenly a crash dialog appeared. Before that, I had opened Eclipse, and had just refreshed all projects and ran "Project -> Clean" on all my projects.

[Comment from a bug triager]
From bug 279180 (KDE SC 4.6.3):
- 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.

From bug 279381 (KDE SC 4.6.5):
-- Information about the crash:
Starting kdevelop from <Alt+F2> (Launch application widget).
Crashes most everytime starting kdevelop
The crash can be reproduced every time.

There is not. But maybe I can find some packager that can create one. Which distribution are you on with exact version?

Please install kdebase-runtime debugging symbols and recreate the backtrace. If it is indeed the crash discussed in this bug report please apply the patch if possible.

No-one has reported this with a KDE version > 4.7.4, and one user reported it fixed in KDE 4.9.2. I also tried to reproduce and couldn't. Someone seems to have fixed it somewhere along the line.
