Issue with include evaluation of filename if namespace is used

[Alec Tiefenthal]

example.xacro

<?xml version="1.0" ?>
<robot name="example" xmlns:xacro="http://www.ros.org/wiki/xacro">
  <xacro:property name="include_file" value="$(find example_package)/child.xacro"/>

  <xacro:include filename="${include_file}" ns="child_ns"/>
</robot>

The above xacro file will fail, complaining that include_file is not defined. This error does not present itself if the ns attribute is not used.

example2.xacro

<?xml version="1.0" ?>
<robot name="example" xmlns:xacro="http://www.ros.org/wiki/xacro">
  <xacro:arg name="include_file" default="$(find example_package)/child.xacro"/>

  <xacro:include filename="$(arg include_file)" ns="child_ns"/>
</robot>

The above file appears to work just fine.

Thanks for reporting this issue. I filed a fix in #264.
