Comment:

 Thanks; fix here

 https://github.com/pv/scipy-work/tree/bug/1353-fix-overwrite

 I'll need to think for a moment before committing it.

 @Ralf: still time to get this into 0.9 --- or just postpone until next
 release (0.9.1 or 0.10)? The use case is not the most common one, but
 still people probably will hit it. A smaller fix can be separated --- the
 main part is that setting overwrite_x=1 after _fix_shape in basic.py is
 not correct.
