gl crashes if directory does not contain a repo with AttributeError: 'NoneType' object has no attribute 'decode'

If I run gl command in a directory which does not contain a git repository, it crashes:

ks-mbp:foo ks$ ls -la

drwxr-xr-x 2 ks staff 64 Aug 7 12:01 .
drwxr-xr-x 219 ks staff 7008 Aug 7 12:30 ..

I cannot even create a repository with "gl init" as it crashes with the same error.

Apparently this behavior was caused by recent upgrade of libgit2 and py27-pygit2 from 0.26.4_0 to 0.27.4. Rolling back to 0.26.4_0 restored normality. Is there any incompatibility between gitless and libgit2 0.27.4?

Thanks for looking into this. A breaking change was introduced in pygit 0.27 (changelog link) but PR #180 fixed it. If you are running Gitless 0.8.6 then you should use pygit 0.26, if are running from HEAD then both pygit 0.26 and pygit 0.27 should work.

The breaking change introduced in pygit2 0.27 is also causing it to crash on gl init. I will cut a new release with the fix soon.
