Comment 9 for bug 750554

Lukas, thanks for answer, but it does not work for me. Source patched, configured and compiled well, configure reports about using LIBNL3, installation fine.
But, running kded4 or kdeinit4 --no-fork gives the same:

Failed to read classid file: Object not found
kded4: symbol lookup error: /usr/lib/ntrack/modules/ntrack-libnl3.so: undefined symbol: ntrack_list_insert_sorted
kded(2910): Communication problem with "kded" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

I've looked into /usr/lib/ntrack/modules/ntrack-libnl3.so by objdump, and found that ntrack_list_insert_sorted is really undefined. I run ldd on this module, on other installation (11.04), and ldd reported about link to libntrack.so.0, which is absent in ntrack-0.15 and 0.14 from your links above. I've changed configure, added "-lntrack" to link options, compile and install - and my issue was gone. I have no patch for this, because I'm not sure, that my correction is right.

Is there need for opening addition bug for this?
