I'm having several problems using nepomuk ad services relying on it (a lot :) ) basically, the simptom is here: (dmesg) nepomukservices[5971]: segfault at 100000000 ip 00007f1f0af54c8f sp 00007f1efd642420 error 4 in libsoprano.so.4.3.0[7f1f0af0f000+ef000] nepomukservices[5979]: segfault at 7f1b2e7aa808 ip 00007f1ccc715fdb sp 00007fff60044e20 error 4 in libsopranoclient.so.1.2.0[7f1ccc6fe000+51000] nepomukservices[6083]: segfault at 100000000 ip 00007fb190fbdc8f sp 00007fb1850bd420 error 4 in libsoprano.so.4.3.0[7fb190f78000+ef000] I tried to follow hints from similar (but seen in older versions of nepomuk) bugs, with no success. Any hint about what's to try? Thanks.

Tried to update to latest soprano (2.7.5) but segfaults are still here. I obtained a core dump, I fear of limited help, but anyway: Core was generated by `/usr/bin/nepomukservicestub nepomukstorage'.

I'm really sorry to not be of any help, but it's the same here. That's why I removed the semantic-desktop entirely from my KDE. nepomuk dies every other minute on simple text files and there seem to be no connections between them, they all look unsuspicious. Maybe it's fixed in 4.8.1? Haven't tried that, but would do so if you say it's worth it.

Maybe it's too early to say something, but yesterday I emerged 4.8.1 and so far no more segfaults from nepomuk/soprano, and file indexing is running. I guess that some days more are needed to be confident of that, but so far so good :)
