Question #153448 on DOLFIN changed:
https://answers.launchpad.net/dolfin/+question/153448

Johan Hake posted a new comment:
Emek!

Sorry for being such a dumass, but what was that you just sent us? Was that a 
diff or patch? I need something that shows the difference between the present 
tip and your improvements. 

I cannot manually go in and apply these changes. That would be too error 
prone. Could you also send me an abaqus mesh which fails for the present 
meshconverter and which is correctly converted with your patch. I can then 
update the unit test.

Johan
