No, it isn't just you :)
The random objects, including trees, are placed randomly based on the terrain
type of the scenery, as defined in materials.xml.
IIRC there is no attempt to stop multiple objects being placed at the same
location - just the random function - and each object type is considered
independantly.
Objects from the scenery objects databased are placed as defined in the
.stg/.btg files. Again, there is no attempt by the random object code to avoid
placing random objects at the same location.
In general this isn't a problem - we don't use object densities high enough to
see "collisions" regularly, and usually a larger object will completely obscure
a smaller one.
If we decide to increase the density of random objects significantly so that
collisions become a problem, we'll probably need to change to a different
scheme, particularly for towns and cities. One possibility is to use a bitmap
to determine possible object locations. This can then be aligned with the
texture, so our buildings align with the streets, trees appear on the edges of
fields, cows in the middle etc.
However, I have enough work on my plate before the 1.9 release to start
thinking about that just now!
