When using gnuplot with 'set term x11', the clients with the plots are named 'null'.
Excerpt from 'subtler -cl':
0xc00008 * 1 836x1046 4 2 (null) ((null))

Trying to tag this client with 'subtler -c null -T gnuplot' segfaults subtler.

'subtler -cxT gnuplot' and clicking the client crashes also, but is more verbose:
