$ zenity --list --title "Select musicians" --text="Some text"
--column="Select" --column="Musician" --checklist --separator="\n"
--height=480 --width=370 < Musicians

The dialogue opens. Now hit OK or Cancel.

Now, sometimes this works, but most of the time the dialogue freeze.
The terminal shows the following:

(zenity:3629): GLib-WARNING **:
/build/buildd/glib2.0-2.32.3/./glib/giounix.c:411Error while getting
flags for FD: Bad file descriptor (9)

and so on.

Ctrl+c in the terminal cancels the dialogue.

Here is an strace example:
strace -tt -ff -o /tmp/zenity zenity --list --title "Select musicians" --text="Some text" --column="Select" --column="Musician" --checklist --height=480 --width=370 < testfile

The file ”testfile” is attached to this message.
