UV Mapping export error?

Hi Guys

Working on my first full model and texture, it is a bus obviously. Anyway I have UV unwrap it a few times now just trying to get it right. I like the UV map now and have gone to “Export UV Layout” Save it as a .PNG and get this error can someone tell me what it means?

I run windows 7 64bit

With blender build 44381


That is a bmesh build. This is not production ready so don’t expect all the addons to work correctly. Try the official 2.62 version.

I feel like an idiot, I completely forgot this is a Bmesh build thanks mate.

Btw it’s been reported:
