The following code generates the error:
Slab Building Error: Cannot use non-perpendicular camera vectors with vista
buffer.
which is a bug because the matrix transform here is not non-perpendicular.
In fact the matrix specified here is the same as a simple translation of
<5,5,5>.
camera {location 0 look_at z matrix <1,0,0,0,1,0,0,0,1,5,5,5>}
I'm using POV-Ray 3.5 beta 1
on a P150, 16MB RAM
Windows 95 4.00.450 B IE 5 5.00.2919.6307

I could be wrong, but shouldn't the last four entries in the matrix be
5,5,5,1? ie,
<1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
Tx,Ty,Tz, 1>

No, the matrix only takes 12 floats, 3 for each of the 3 local axis and 3
for the translation. The fourth column is used internally in POV-Ray only.
Could somebody confirm the bug report I posted?

I get a different warning:
"Warning: Camera vectors are not perpendicular.
Making look_at the last statement may help."
Just copied your camera-statement, no objects.
Wait! I get your error message, if I add 3 objects to the scene. IRC the
vista buffer is not used with less objects in the scene.

My fault, I have the Bounding_Threshold set to 0 in my main povray.ini file.

Thanks for the confirmation.
