Hello

This script

 setenv("GNUTERM", "qt")
plot([0 1],[0 1]);

 returns the error

(gnuplot_qt:20247): IBUS-WARNING **: Unable to connect to ibus: Could not connect: Connection refused

after this plotting results are unpredictable

no error is returned if the setenv command is ommited (but cairo graphics are not available)

Unknown or ambiguous terminal name 'qt'

The "Unknown ...." message only shows up once.

The line is properly drawn each time.
