So how up to date is your poky meta data, mine is as of this afternoon  that contains 2 bug fixes that relevant to meta-toolchain build.  Also, seems you're using the build system derived toolchain?  If so, I can give that a try...

Hi Jessica,

Thanks for your reply.

I am using the build system derived toolchain. I am using the latest 
poky.git as of 9:22am GMT 9th Jan. I am using the eclipse-plugin master 
branch. I tried again this morning and encountered the same error.

To run the eclipse plugin I am using the method of adding the source 
code to the eclipse project and then right clicking and running as an 
eclipse program. However I believe the issue is either with my Python, 
or with some other incompatibility in the script.

Best Regards,
Jack.
