The extension works correctly if I disable LaTeX support, but I'm creating a diagram for use in a LaTeX document so I'd rather keep it on if at all possible. That suggests that the problem is to do with LaTeX, though.

As per issue #4, I tried installing pstoedit (I didn't have it before), but I still get the same error. Any ideas?

it seems latex is not creating the pdf of yout latex code;

I am uploading soon a newer version of InkscapeMadeEasy that might solve this issue.
