Are you looking at structured data in a 2D view? If so this is
probably the bug I fixed around the 3.8 time frame with:
commit 78da8a8e1132f2ea62f920038d67937a37cdfba6
Date:   Tue Jun 8 10:39:36 2010 -0400
If so, bump to a newer release it should be fixed.

I believe this is saying that the Qt you are using wasn't properly
configured/built/installed. I've run into problems like this with some
Qt binary installations on some platforms (most often Mac) so I tend
to build Qt from source myself.

If you have built ParaView from source, you can turn off the GUI. The
server doesn't need Qt so this problem should go away if you build
ParaView without it.
