Remove the initial_clock and final_clock from your ini.

The rotation of the camera assume that you use a "standard" clock whose 
value change in the 0~1 range.


change the *360 by *90.

Personaly, for an animation, I almost never use an ini file, but use the 
command line option:
+kff4
for a 4 frame animation of the currently open scene file.
For a full circle rotation, it's usualy advisable to add +kc. 
cyclical_animation=1 if using an ini file. Otherwise, the first and last 
frames will be identical.
+kff4 +kc
