Hi,

I run KDE 4.11.2 on Arch linux and ever since 4.11.0 I observe crashes of file indexer in the journalctl logs.

paź 04 12:45:44 blaszak systemd-coredump[15998]: Process 15385 (virtuoso-t) dumped core.
-- Subject: Process 15385 (virtuoso-t) dumped core
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/li ... temd-devel
-- Documentation: man:core(5)
--
-- Process 15385 (virtuoso-t) crashed and dumped core.
--
-- This usually indicates a programming error in the crashing program and
-- should be reported to its vendor as a bug.

It is a kinda annoying, and I wish I could renable this feature again.

logs do not appear to be helpfull here.

I used to think that disabling pictures indexing can help, but it didn't. The above log comes from the system with disabled pictures indexing (strange, but true).

soprano-virtuoso.log contains the following:

Can somebody help me? I'm going nuts here

Ok, I think i was able to solve it.

I disabled image indexing and then removed nepomuk database and recreated it once again. It seems that those errors from logs are gone.

How to help solve this bug? I can provide files that crash nepomuk file indexer.

I would suggest:

Create a temporary directory and copy one of the offending images to it.

Start kdebugdialog
Enter nepomuk as the search string
Select All > Apply > OK

Start konsole and navigate to the location of the offending image.
Then, at the prompt, enter nepomukindexer [filename.ext]
Tthat will force nepomuk to attempt to index the file and display any errors.
Create a bug report at http://bugs.kde.org/ attaching the offending file and a copy of the error output.

Don't forget to run kdedialog again to deselect all after you have finished testing.

Please note that this is a crash in Virtuoso, not any component of KDE or Nepomuk. Which version of Virtuoso are you using?

I was running the newest one at the time.

IIRC Virtuoso 6.1.6 has some issues with Nepomuk (but as far as I know, nothing related to crashes).

Please provide the output of the following command:
