kwrite spams console when editing xml file

In a console I ran "touch /tmp/test.xml" and then ran "kwrite /tmp/test.xml &"

In kwrite I typed in the following:
<foo>
    <bar />
</foo>

While I typed this simple example the following was output to the console (in blue):
0
<foo>

-1
>
1

<foo>
0

1
    <bar /
<foo>
0
/
1
    <bar />
<foo>
0
>
2

    <bar />
4

2
    </
    <bar />
4
/
2
</foo>
    <bar />
4
>
3

</foo>
0

(end console output)

I expected there to be no output to the console. If the file does not exist on disk when editing, then the console receives no output.
