Hi Thomas,
did you install gnuradio from the Fedora repositories? Which version do
you have?
Just a couple of threads ago someone else had problems with Fedora
packages; they are not up to date.
Try grabbing a current version from the web site and build it yourself;
it's not that hard.

Even in an old version, this should not happen. However, if you do have
an old version, I recommend upgrading to at least 3.3.0 and trying
again. Once it works, you'll simply have much more fun (read:
functionality) with a newer GNU Radio.
If you do want to debug you installation, a nice place to start might be
by starting the Python command line and plugging together tiny flow
graphs by hand, to see wether or not they crash.
Cheers
