Hi,

There is also another bug report about all these crashes in general 
https://bugs.kde.org/show_bug.cgi?id=301453

Also, according to Manu Tortosa, indeed kde 4.8.4 works without crashes with 
the newer, beta soprano..

I inspected the soprano git repository and I found this commit:
http://quickgit.kde.org/index.php?p=soprano.git&a=commit&h=3d66d429cb48781881af3e735f2a80af2114ab25

which was done the same day than the commit mentioned in the above bug report
https://bugs.kde.org/show_bug.cgi?id=301453#c2

So I built and install kdelibs reverting the commit mentioned in the comment 
#2, this hacked version of kdelibs has been making the crashes gone so far for 
me.

I have checked the debug output for gwenview with a system with the official 
4.8.4 kdelibs, I'm attaching it  as gwenview_stdout_crashing.txt. I did the 
same with a system with the hacked kdelibs, I'm attaching that output as 
gwenview_stdout_working.txt

Note that the working gwenview produces just one line like this:
gwenview(3899)/nepomuk (library) {anonymous}::GlobalModelContainer::init: 
Connecting to local socket "/tmp/ksocket-santa/nepomuk-socket"
while the crashing gwenview tries to connect to that socket various times.

Also note that if I remove /tmp/ksocket-santa/nepomuk-socket the crashes are 
gone.

So I also built a hacked soprano; this hacked soprano is 2.7.6 patched with 
these couple of commits:
http://quickgit.kde.org/index.php?p=kdelibs.git&a=commit&h=a43824a200ed76cef48a90bd3aee8547698b7c91
http://quickgit.kde.org/index.php?p=soprano.git&a=commit&h=5dde64227186d405f86bf66256705fbceabcf1e2
Installing it in an affected system makes the crashes vanish.

Therefore, I tend to think the kdelibs commit mentioned in that bug report 
(3d66d429cb48781881af3e735f2a80af2114ab25) shouldn't have been done for 4.8.4. 
A confirmation from a Nepomuk developer would be highly appreciated.
