switching the order removes the segmentation fault. So for now I won't
recompile. Lets see what I'll encounter down the road.
Thanks for your time,

Problem seems to be in libQt. Would it help switching the import order?
import pylab
import dolfin
Or there's conflicting Qt lib, check that DOLFIN and pylab link to the
same:
$ ldd /path/to/fenics/lib/libdolfin.so | grep -i qt
$ # check pylab, don't know how
Or you could recompile dolfin without Qt (it's practically useless
dependecy, see plot-qt demo)
Jan: maybe you could propose on the mailing list to remove QT as an
optional dependency?

Do you need "set solib-search-path" or "set sysroot"?
