Glowing fish causing debugs?

[Hermes]

Hi there. How can I fix item "glowing fish", it's causing client debug when player sees it.

	<item id="8713" article="a" name="glowing fish" plural="glowing fish">
		<attribute key="weight" value="520"/>
	</item>

note. other "glowing" (tutorial) items are not causing any problems.

I am using TFS0.3.1

Thanks,
Hermes
