dgesdd error

Apparently some dgesdd libraries don't actually compute the correct 
value for the work-space size if requested. 

This results in an ** ILLEGAL value and program termination from LAPACK.

I've added code in the latest SVN to that particular wrapper to make 
sure the query gives back the minimums at least, but I'd like to see who 
else has the problem.

On my system, doing numpy.linalg.svd on a 25 x 50 array pulled the trigger.

Anybody else have that problem with their lapack library?
