Code review comment for lp:~fluidity-core/fluidity/gmsh-on-sphere

Code looks good at a quick eyeball.

Build queue is showing red:

unittests:
    Warnings: 1; tests = ['./test_empty_populate_state']
    Failures: 1; tests = ['./test_empty_populate_state']

Medium tests:
Summary of test problems with failures or warnings:
fladapt.xml: F

Any ideas?
