Segmentation Fault when using Graph plugin

Hello!

I tried to run the following example code in the Help document for the graph plugin:

%xypic -width 300
\xymatrix {
 1\ar[rd] & 2\ar[rd] \ar[d] & 3 \ar[d] \\
 1 & 3 & 5 \\
 1 & 4 & 8
 \ar"2,1";"3,2"
 \ar"2,2";"3,2"
 \ar"2,2";"3,3"
 \ar"2,3";"3,3"^{+3}
}

However, after copying this into the graph plugin window and pressing Shift-Return, I get the Segmentation Fault error enclosed below. I'm using Ubuntu Linux 22.04. Any help is much appreciated!

Best wishes,

Antonio
