Hi Konrad,

I think I might have an answer now. Could you please follow these two
steps and let me know if things work for you:

(1) Add the following lines to your urdf

 <link name="world">
    <inertial>
      <mass value="0.05" />
      <origin xyz="-0.0 0.0 -10.0" />
      <inertia ixx="1.0" ixy="0.0" ixz="0.0"
               iyy="1.0" iyz="0.0"
               izz="1.0" />
    </inertial>

    <collision>
      <origin xyz="0 0 0.15" rpy="0 0 0" />
      <geometry>
        <box size="0.4 0.4 0.3" />
      </geometry>
    </collision>
  </link>

  <joint name="base_joint" type="fixed">
    <parent link="world"/>
    <child link="base_link"/>
  </joint>

This anchors your robot in the world with a dummy fixed link.

(2) Apply the attached patch to a cturtle version of the
motion_planners stack directory. (I am assuming you are working with
cturtle).

Try again with these changes and let me know - if they work for you, I
will push them out into cturtle. For your reference, I have also
attached a tarred version of the planning files that I used to
configure the planner for your robot. Some of these issues are
currently fixed in trunk but it might take us a while to push out a
release from trunk into cturtle, hence the patch.

Regards,
Sachin
