Description Anders Lund 2012-01-08 21:14:58 UTC 
Version:           4.1
OS:                Linux

I let archlinux update soprano to v. 2.7.4, but after that starting a kde session, the file indexing would not run, nor the nepomuk kcm. And it appears that I lost all rating done with bangarang somehow, after downgrading again.

Reproducible: Didn't try

Steps to Reproduce:
adfæghjndf


Actual Results:  
sdlgas

Expected Results:  
dsfdgashb

OS: Linux (i686) release 3.1.7-1-ARCH
Compiler: gcc
Comment 1 Alejandro Nova 2012-01-19 23:47:28 UTC 
This is no Arch Linux bug. Same results, but with soprano 2.7.4 compiled from source, and with soprano-trunk compiled from git.

Reverting to soprano 2.7.3 fixed the issue.
Comment 2 Anders Lund 2012-02-27 15:54:14 UTC 
I am currently running kde 4.8 with soprano 2.7.4.
I can often but not always start a kde session, and nepomukserver is running, and the nepomuk kcm can sometimes run, but nepomuk is very often in a broken state. It is not possible to find out why that is the question though, but the behavior with kde 4.8 + soprano 2.7.4 was similar.

I have had to turn all indexing off once again today, after attempting to starting kde made plasma-desktop go into infinite 100% cpu usage. After the last reboot, nepomuk is in a broken state - searching the exisging index using krunner does not work, and my activity icons are not displayed. It did work for a minute or so during the day.
Comment 3 Franz Trischberger 2012-03-02 08:10:06 UTC 
Same here. dmesg shows messages like this:

Nepomuk is not usable after then, applications got to consume 100%. Here it is kontact. Attaching gdb to the process gives that:

Comment 4 Alejandro Nova 2012-03-03 10:29:10 UTC 
Whatever the problem was, soprano 2.7.5 fixes it.

Also, see bug 292388; it's a duplicate.
Comment 5 leo_rockway 2012-03-04 17:27:54 UTC 
I can't confirm that 2.7.5 solves it.

$ dmesg | tail -1

Comment 6 Franz Trischberger 2012-03-08 08:14:36 UTC 
No segfault reports anymore in dmesg with soprano-2.7.4 and kde-4.8.1 - now kontact segfaults directly. Don't know what's better - freezing or crashing :D
When this happens the next time, I will attach a backtrace.

But soprano is not directly involved; I had another BT, where Soprano-classes were in the BT, thoough I think it was a reallocation-error, too. Will see, if I can get it again.

Downgraded to 2.7.3, yesterday morning, and no crash anymore - until now.

It is crashing in Soprano. So probably all this is not an issue within soprano, but in kde-4.8? (nepomuk)

(BTW.: Do you want the whole output DrKonqui presents, or is it enough to post the relevant part - the one with [KCrash Handler] on top?)
Comment 9 David Faure 2012-07-13 16:38:21 UTC 
The backtrace in comment 7 (crash in addResource) is bug 295802, which I'm about to fix. Not sure the rest of this report is related, though.
Comment 10 Vishesh Handa 2013-06-10 13:01:34 UTC 
This bug addresses multiple issues. All of them have been fixed.
