Sure can. Graph is as follows:

[Null Source] ---> [UHD SINK]
[UHD Source] ---> [Null Sink]


Results are as follows:

Options Block/Generate Options set to QT-GUI : Runs Fine
Options Block/Generate Options set to WX-GUI : SEGV
Options Block/Generate Options set to No-GUI : SEGV

Also added a "NOP" block in-between the sources and sinks,
same result.
