I do not see this error in latest trunk of numpy (I suspect it's also 
not there in the latest release).

It was a bug.  A segfault with pure Python is *always* a bug (unless you 
are using ctypes).

Which situation is this exactly? 

Thanks for the report.   Don't forget about the Trac pages where bugs 
(filed as "tickets") can be reported, checked, and fixed.   See the 
www.scipy.org site under the Developer tab for more details.

Best regards,
