According to David Faure (comment 15 in #163171), this is a nepomuk/soprano crash. Well are u sure both Crashs are the same? It looks kind of different ;) Lukas Are you talking about the valgrind vs gdb backtrace? If I don't attach valgrind, kget crashes with the gdb backtrace posted above. If I attach it, I get the valgrind output. I did this 3 times, it's 100% reproducible here. Also, it appears that every file download makes kget crash. Ok, well seems very much like a Soprano/Nepomuk issue... Lukas Some more kget/kioslave crashes. If I turn on konqueror integration and click apply:
