Details:

The readline function 'operate-and-get-next', which is bound to Ctrl+o by
default, causes the GUI to crash with a segmentation fault. When running in
terminal mode there is no crash. Binding Ctrl+o to a different readline
function works fine, so it appears specific to the 'operate-and-get-next'
function.
