This is not a bug. It can be simplified as:

$ echo '
> ^D
bash: unexpected EOF while looking for matching `''
bash: syntax error: unexpected end of file
$ ^D
<bash closes>

A ^D (Ctrl+D) sends an EOF.

If you have a command with incomplete quoting when it reaches EOF,
bash complains "unexpected EOF while looking for matching" and stops
the parsing.

At this point you are at a normal shell prompt, not continuing the
previous command.
If you do a Ctrl-D instead of entering any command, bash finishes. And
the tty is closed when the shell finishes, as well as your xfce4-
terminal tab (some terminal emulators have a configuration setting for
not closing the tab, though). It's not a crash.
