crash when disconnecting line-plot x input

[chrisvam]

If I run this command and then disconnect the X input to the line plot then I reproducibly get a crash: ami-local -l ~/padded.fc -b 1 -f interval=1 psana://exp=tmolw5618,run=99

Full output is here:

In a previous crash doing the same thing, I got a much more ugly/verbose output:
