WMS GetFeatureInfo bug?

[Barend K=?ISO-8859-1?B?9g==?=bben]

When trying to issue GetFeatureInfo requests to Mapserver (4.10.0 on WinXP),
I notice some strange behaviour:

Despite requesting (and getting) INFO_FORMAT=text/plain, my requests won't
work, an exception "WMS server error: Requested layer(s) are not Queryable"
is returned. If I do specify in the map file for every CLASS in a LAYER a
"TEMPLATE" "somepath/anytemplate.html", it works, although my info is still
returned as text/plain(as requested). It even works when the template file
mentioned does not exist!

It looks like a bug, or am I missing something...?
