Yeah. So Nepomuk is the cause of the problems -

Here our our options -

1. I revert Sebastian's commits in kdelibs. This should fix the issue, but we would need to reintroduce the changes for 4.9, and since we do not have separate branches ...

2. Sebastian should release a new version (2.8) of Soprano any day now, packagers will need to get everyone to update.

Or

I already wrote it in another bug report, that I extracted a patch from the
diff between 2.7.6 and 2.7.56, that simply introduces Soprano::Socket to the
2.7.6 Codebase - and all those crashes are gone, now running >2 days without a

We do as suggested over here.
 

Is it possible, to release soprano-2.7.6.1 or so, that ships with
Soprano::Socket? This would make it possible for distributions to ship a
working kde-4.8.4 with only stable software.
