Oh, sorry for not coming back to you. I must admit that I didn't try your 
suggestion because I got a new laptop and I installed Kubuntu on that (where 
the problem does not exist).

However, it seems that my 'One uses -pthread instead of -lpthread on FreeBSD' 
information was maybe outdated - somebody on #kde-freebsd pointed out that I 
could use '-lpthread' as a configure argument for Qt, and that supposedly 
fixes the problem I had.
