According to cairo/CODING_STYLE tabs are always 8 spaces, so 
detabification should not be necessary to line things up. And I
certainly will not guarantee that tabs don't come back, (they
certainly appear in any files that I edit).

This one is my fault. I fixed a bug in that it wasn't doing error
checking here, but I didn't know how to fix the leak. So thanks.
I've now committed this bug fix.
