I've actually got it to work for a while, but at some point it stops. I managed to 
catch a backtrace (attached). The nepomukserver log is also attached. I'm using 
virtuoso 5.0.12 and qt 4.6 from git.

I'm not sure what actually triggered the crash, though. After the crash, it seems 
that I also need to kill virtuoso, otherwise I won't get any search results. It 
doesn't seem to pick up the connection to the running virtuoso.

Something else that struck me is that files opened from searching for example in 
Dolphin doesn't point them to the right location. Sometimes the file doesn't open 
(maybe a temporary url?). It looks like this:

The file or folder nepomuksearch:/hastag:KDE/nepomuk_3A_2Fres_2F42d135f8-6ff9-48a6-
b722-98ba6439accd does not exist.

Opening files from the search dialog works, although it doesn't point to the original 
location when saving files.
