Note that I get frequent freezes with similar backtraces when I attach GDB, and these seem to be related to Nepomuk as well (see Bug 203668).
Comment 6 Dario Andres 2010-03-20 15:21:55 UTC 
This could be related to bug 224102 or bug 230520 (but those don't have Nepomuk/Soprano calls; only dbus stuff)

krunner crashed after starting two applications using it. nepomuk is disabled.
Comment 23 Alex Merry 2010-06-02 13:46:58 UTC 
This is, in fact, a D-Bus threading issue.  libdbus-1 claims to be more thread-safe than it is, and both Nepomuk and KRunner make heavy use of threads, and make D-Bus calls from those threads.

See http://lists.kde.org/?t=127496858200006&r=1&w=2 and https://bugs.freedesktop.org/show_bug.cgi?id=17754 for more information.

There is a patch for libdbus-1 (http://lists.freedesktop.org/archives/dbus/2008-January/009100.html) which should hopefully make it into dbus-1.4.0 (http://lists.kde.org/?l=kde-core-devel&m=127499327531026&w=2), but that is still some way off.

Note that if you run Arch Linux, you can replace dbus-core with a patched version (http://aur.archlinux.org/packages.php?ID=37728), but I provide no guarantee that it won't break non-KDE software.

I'm resolving this bug as UPSTREAM, since the correct place for the fix is in D-Bus; even though Nepomuk in KDE 4.5 includes a workaround for the issues, it is not very effective (I still get crashes without a patched libdbus-1).
