Hi, Peter Penz <peter.pen...@gmail.com> > The issue has been tracked at > https://bugs.kde.org/show_bug.cgi?id=268064 - updating Soprano to the > latest master resolves the crash.

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.
