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.

OK, but were these sending/receive from the USRP1 simultaneously, in the
same flow-graph?
They was within the same GRC File, although not linked (IE separate
RX and TX chains)
The case I'm interested in is where there's only one of those at a time.
I just tried [UHD SOURCE] -> [MULTIPLY CONST] -> [UHD SINK], and that
worked with all three Options Block/Generate Options settings.
[UHD SOURCE] -> [MULTIPLY CONST] -> [WX WATERFALL SINK] has always
worked.
Just having one "chain", RX or TX has always worked for me, even with
the WX GUI sinks.
Hope that helps
Iain
