calling setRotation() causes a Fatal Error

[byteterra@…]

I use the MS4W (mapserver 4.10) package with PHP5 on a PC with WindowsXP Pro
with Apache 2.0.59 and I noticed that calling:

$map->setExtent()
$map->setSize()
$map->setRotation() 

(the sequence matters) causes an error at the line that calls setRotation().

Fatal Error: [MapServer Error]: msCalculateScale(): Invalid image width or height

However, if I use the following sequence

$map->setSize()
$map->setExtent()
$map->setRotation() 

it seems to work.

I've prepared a small example that demonstrates this behaviour. Here's the
download link: http://terra.newstrekker.com/setrotation.zip

Note that the EXTENT and the SIZE are not set in the mapfile itself.
