[Gate-users] trouble with ring repeater

Hello GATE users,

I installed Gate_v3.0.0 together with Geant4.8.1.p01 successfully a few days ago on SUSE Linux 10.1 OS. I am new to Gate and first tested the installation by running a few test macros.

As soon as ring repeater commands are implemented, the system does not function as expected: the rotation is performed along the center axis of the object resulting in multiple rotated copies at the same location after the following two commands: 

# R E P E A T R S E C T O R
/gate/box1/repeaters/insert ring
/gate/box1/ring/setRepeatNumber 30

I have included an example macro from the Gate Users Guide below.

I regularly get the following output: 
world_L is registered to the default region.
  Volume of the same name and copy number ("world_P", copy 0) still exists and is being used.
  Be warned that this does not necessarily guarantee it's the same 
  volume you originally specified in /vis/scene/add/.

Is it possible that the above commands are not valid anymore, as was the case for the
/vis/viewer/viewpointThetaPhi command which had to be adjusted to /vis/viewer/set/viewpointThetaPhi ? 

I also made a second install of Gate_v3.0.0 linked to Geant4.8.0.p01 libraries, but this did not resolve the issue. Does this sound familiar to anyone?
