[Discuss-gnuradio] No scope with gr?

[Ralph A. Schmid, dk5ras]

Hi,

With latest gnuradio the scope view refuses to work in my flowgraphs.
Execution ends completely without any error message. Removing the block and
putting it newly into the flowgraph changes nothing. Disabling the scope
makes the projects work, the water fall works without issues. 

Uninstalling gnuradio, deleting the build folder and rebuilding everything
changed nothing. All elements are built, cmake seems to be fine with the
prerequisites, still no working scope.

Kubuntu 14.04 64 bit, latest kernel and all other updates, gnuradio from
sources (master), no pybombs...

Where can I start searching for the reason?

Thx!

Ralph.
