Hi all, I found the following thread: http://lists.kde.org/?t=132932694700004&r=1&w=2 but I can't reply there since I just got subscribed to the mailing list... So, please, apologize me for starting a new thread... :) I compiled the soprano and kdebase-runtime with debug symbols and I attached to all nepomukservicestub process with gdb -p <PID> and here what I got for nepomukservicestub nepomukstorage: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7f19b97fa700 (LWP 5814)] 0x00007f19ef2ddeef in Soprano::Node::toN3 (this=<optimized out>) at /home/insane/Development/oss/archlinux/extra/soprano/src/soprano-2.7.4/soprano/node.cpp:252 252 return d ? d->toN3() : QString(); Yes, it's not a complete stack trace, but I'm new to gdb and I don't know how to get a useful stack trace. Anyway, I hope this will give some hints what the problem is. I'm willing to help debug this issue and I hope it'll get fixed before 4.8.1 since it makes the whole desktop behave rather odd (activities, mail search, etc.). If there is already an open bug, please, give me a link - I couldn't find a bug, though...
