Hi all,

if I use a qt-gui sink in a flowgraph I get a segmentation fault on the
tb.stop() call.
That is a problem as I use this together with a wavfile-sink.

Due to the segfault  the wav file  header is not written and I have to
use a hexeditor to correct the header data to be able to read the
samples in a wavfile source.

The segfault even happens if I remove the wavfile-sink.
A small example is attached.

I'm using gnuradio from git together with gentoo 64 bit linux.

Thanks in advance

Volker
