Unloading libraries is always a recipe for disaster. You can't unload if there
are threads running or other things still allocated. That's probably the
reason why you get that segfault when you try to unload it.
Now, none of the libraries has -z nodelete, so the only thing that would keep
it from unloading are plugins. And besides the designer/libqwebview.so plugin,
I can't see any other plugin linked to QtWebKit.
Anyway, my suggestion is: don't try. Just forget about unloading the libraries
